Abstract:
The more massive component star evolves faster than the less massive one. When it fills its inner critical Roche lobe at the red-giant stage or at the asymptotic-giant-branch (AGB) star stage, the mass transfer begins from the more massive to the less massive component. Since the separation decreases with the mass being transferred, the more massive component star eventually overfills its outer critical Roche lobe. The mass outside the outer critical Roche lobe flows out of the system and the outgoing matter carries away the orbital angular momentum. As a result, the separation of the binary shrinks and the size of the outer critical Roche lobe drops. This shrinkage of the Roche lobe enhances the systemic mass outflow. This process is almost dynamically unstable because the deep convective envelope responses the loss of the envelope mass in an almost dynamical time scale. This dynamical process will stop when most of the hydrogen-rich envelope of the more massive component is lost and its radius becomes less than the radius of the outer critical Roche lobe.

Abstract:
ABSTRACT We present ULTRACAM multiband optical photometry of two transitional millisecond pulsars (tMSPs), PSR J1023+0038 and PSR J1227−4853, taken while both were in their radio pulsar states. The light curves show significant asymmetry about the flux maxima in all observed bands, suggesting an asymmetric source of heating in the system. We model the light curves using the icarus binary code, using models with an additional ‘hotspot’ heating contribution and an anisotropic heat redistribution model to treat the asymmetry. Our modelling reveals companion stars with underfilled Roche lobes in both PSRs J1023+0038 and J1227−4853, with Roche lobe filling factors in the range f ∼ 0.82−0.92. While the volume-averaged filling factors are closer to unity, significant underfilling is unexpected from tMSPs as they must rapidly overfill their Roche lobes to start transferring mass, which occurs on time-scale of weeks or months. We discuss the motivation and validity of our extensions to the models and the implications of the underfilled Roche lobe, and suggest future work to further investigate the role of the filling factor in the tMSP cycle.

Abstract:
ABSTRACT The Roche lobe formalism describes mass transfer from one star to another. We develop an extension to hierarchical triples, considering the case in which a star donates mass to a companion which is itself a binary. The L1 point moves as the inner binary rotates, and the Roche lobe pulsates with the period of the inner binary. Signatures of mass transfer may therefore be imprinted with the orbital period of the inner binary. For some system parameters, the pulsing Roche lobe can drive mass transfer at high rates. Systems undergoing this type of mass transfer include those with inner binaries consisting of compact objects that will eventually merge, as well as progenitors of Type Ia supernovae.

Abstract:
AbstractDifferent types of massive interacting binaries with Be components are discussed. Due to mass exchange, Be stars in these systems have some peculiar characteristics. Often it is even difficult to find traces of the Be star and/or mass-losing star in the optical region of the spectrum. Using the value of the orbital period as a primary parameter, it is possible to divide all massive interacting binaries into two large groups: short-period or classical Algols and long-period binaries. The last group includes a number of very active mass transfer systems named as W Serpentis. There is also a small group of double systems whose stars do not fill their Roche lobes but have emission lines in the spectrum. Properties of their spectral variability are discussed. Analysis of each group lets us find different behaviours in mass exchange that depend on the size of their Roche lobes.

Abstract:
AbstractWe present a series of time-dependent 2D and 3D numerical simulations illustrating the evolutionary sequence between high mass X-ray binaries fed by wind accretion (where the primary star sits well within its critical tidal lobe) and those fed by Roche lobe overflow (where the primary star extends out to its tidal lobe). When the primary lies well within its critical surface we find negligible tidal mass loss enhancement, and a system that is characterized by wind accretion with the development of a photoionization zone around the compact object. As the surface of the primary nears the critical surface, we observe tidally enhanced mass loss via a thin tidal stream, resulting in higher accretion wake densities. For full RLOF we observe the development of a steady accretion disk characterized by a total shadowing of the X-rays in the orbital plane.

Abstract:
Ultraluminous X-ray sources (ULXs) have such high X-ray luminosities that they were long thought to be accreting intermediate-mass black holes. Yet, some ULXs have been shown to display periodic modulations and coherent pulsations suggestive of a neutron star in orbit around a stellar companion and accreting at super-Eddington rates. In this Letter, we propose that the mass transfer in ULXs could be qualitatively the same as in supergiant X-ray binaries (SgXBs), with a wind from the donor star highly beamed towards the compact object. Since the star does not fill its Roche lobe, this mass transfer mechanism known as “wind Roche lobe overflow” can remain stable even for large donor-star-to-accretor mass ratios. Based on realistic acceleration profiles derived from spectral observations and modeling of the stellar wind, we compute the bulk motion of the wind to evaluate the fraction of the stellar mass outflow entering the region of gravitational predominance of the compact object. The density enhancement towards the accretor leads to mass-transfer rates systematically much larger than the mass-accretion rates derived by the Bondi-Hoyle-Lyttleton formula. We identify orbital and stellar conditions for a SgXBs to transfer mass at rates necessary to reach the ULX luminosity level. These results indicate that Roche-lobe overflow is not the only way to funnel large quantities of material into the Roche lobe of the accretor. With the stellar mass-loss rates and parameters of M101 ULX-1 and NGC 7793 P13, wind Roche-lobe overflow can reproduce mass-transfer rates that qualify an object as an ULX.

Abstract:
Some close-in gaseous exoplanets are nearly in Roche lobe contact, and previous studies show that tidal decay can drive hot Jupiters into contact during the main sequence of their host stars. Improving on a previous model, we present a revised model for mass transfer in a semidetached binary system that incorporates an extended atmosphere around the donor and allows for an arbitrary mass ratio. We apply this new formalism to hypothetical, confirmed, and candidate planetary systems to estimate mass-loss rates and compare with models of evaporative mass loss. Overflow may be significant for hot Neptunes out to periods of similar to 2 days, while for hot Jupiters, it may only be important inward of 0.5 days. We find that CoRoT-24 b may be losing mass at a rate of more than an Earth mass in a gigayear. The hot Jupiter WASP-12 b may lose an Earth mass in a megayear, while the putative planet PTFO8-8695 orbiting a T Tauri star might shed its atmosphere in a few megayears. We point out that the orbital expansion that can accompany mass transfer may be less effective than previously considered because the gas accreted by the host star removes some of the angular momentum from the orbit, but simple scaling arguments suggest that the Roche lobe overflow might remain stable. Consequently, the recently discovered small planets in ultrashort periods (< 1 day) may not be the remnants of hot Jupiters/Neptunes. The new model presented here has been incorporated into Modules for Experiments in Stellar Astrophysics (MESA).

Abstract:
Le travail présenté est constitué de trois parties indépendantes. Dans la première partie, on étudie à l'aide de la technique SPH (Smoothed Particle Hydrodynamics) la déformation du secondaire au contact de Roche dans les variables cataclysmiques (CV). Ces déformations conduisent à une période orbitable plus grande que celle prévue par la troisième loi de Képler. La prise en compte de cette modification dans des modèles dévolution de CV explique partiellement pourquoi la période des CV observées a un minimum vers 80 minutes. La deuxième partie traite des binaires serrées de naines blanches. On présente un modèle analytique simple du transfert de masse dans ces systèmes lorsque le secondaire remplit son lobe de Roche. L'étude montre que si le rapport des masses est petit (secondaire légerà, alors de transfert de masse est stable et dure typiquement cent millions d'années. Dans le cas contraire, il est instable et la coalescence complète se produit en quelques minutes. Une modélisation SPH montre le déroulement de cette coalescence. La troisième partir concerne le refroidissement des naines blanches isolées pour donner une relation âge-luminosité de ces objets. Le refroidissement est étudié à l'aide d'une code d'évolution stellaire qui calcule complètement la structure de l'étoile (équation d'état, de transfert d'énergie, du mouvement)̀. Ce code est adapté pour traiter la cristallisation du plasma dans le cas d'une composition pure (C ou O) ou d'une mélange (C+O). L'allongement du temps de refroidissement à cause de la cristallisation est étudié. Les courbes de luminosité correspondant à différentes masses sont présentées.

Abstract:
In questo elaborato viene esaminata la Teoria del Lobo di Roche, messa in luce dall'astronomo Eduard Albert Roche. Per poter affrontare questo argomento, inizialmente si è introdotta l'Evoluzione Stellare e le sue fasi principali; in seguito si è descritto il concetto di Sistema Stellare Binario e i due metodi per poterli classificare. Successivamente vi è una trattazione prettamente matematica riguardante l'individuazione dei punti di equilibrio sotto l'influenza della forza gravitazionale e le rispettive superfici equipotenziali generate. A questo punto, il calcolo esplicito di tali punti di equilibrio è di fondamentale importanza per il trasferimento di massa tra le due stelle che compongono il sistema stellare binario, che verrà descritto sia per sistemi stellari di piccola massa che di grande massa. Infine vengono date applicazioni sperimentali di trasferimento di massa con effetti di feedback positivo e negativo in sistemi stellari. L'elaborato si conclude con la constatazione dell'esistenza dei punti lagrangiani in ogni sistema binario, compreso quello del sistema Sole-Terra, per il quale viene calcolato esplicitamente il punto L2.

Abstract:
Les réservoirs clastiques sont constitués pour la plupart d'un agencement géométrique de plusieurs structures. Le but de ces travaux est de fournir une représentation volumétrique de ces différents objets afin de pouvoir reproduire la grande hétérogénéité des dépôts sédimentaires. Nous proposons une paramétrisation tridimensionnelle compacte des objets sédimentaires qui permet de représenter des géométries variées et qui fournit un espace curvilinéaire pour la modélisation des hétérogénéités internes des structures sédimentaires. Les modèles de corps géologiques sont définis par une représentation par frontières, chacune des frontières étant construite par une surface paramétrique déformable. La formulation mathématique utilisée pour construire les espaces paramétriques sont les B-Splines rationnelles non uniformes dites NURBS (pour Non Uniform Rational B-Splines). Chaque forme élémentaire est contrôlée par des règles de déformations afin de maintenir la géométrie et la cohérence des objets durant l'édition. Les modèles de structures sédimentaires sont appliqués à la simulation de chenaux et des structures qui y sont liées telles que les barres d'accrétion latérale. Ils servent alors de support pour réaliser des simulations de propriétés pétrophysiques qui suivent l'espace paramétrique particulier de chaque objet. Les modèles d'objets sédimentaires sont également appliqués dans le cadre de l'interprétation semi-automatique d'images géologiques en adaptant des méthodes classiques d'extraction de formes. Cette approche est appliquée sur des images satellites de chenaux alluviaux. Des résultats préliminaires sur des données de sismiques 3D sont également présentés
Most clastic deposits consist in geometric arrangements of several structures. The purpose of this work is to provide a volumetric representation of these objects in order to reproduce the high heterogeneity of the sedimentary deposits. These models are constructed to be flexible and compact in order to model the sedimentary formations at different scales. The sedimentary models are defined by a boundary representation ; each boundary is defined by a deformable parametric surface. The proposed parametrization is the Non Uniform Rational B-Spline (NURBS). Each elementary shape is controlled by deformation rules and has connection constraints with associated objects, in order to maintain the geometry and the consistency through editing. Sedimentary structure models are applied to channel simulation and to the construction of the related structures such as point bars. These structures are then used as framework for petrophysical property simulations. The models are also applied to semi-automatically interpret geological images by adapting classical shape extraction methods. This approach is applied on satellite pictures showing alluvial channels and some preliminary results on 3D seismic time slices are also presented

Lone-parent family households in Czech and Slovak Republic after 1970 in the context of socio-economic and demographic development. Abstract This paper introduces the topic of families and households. The shift of attitudes and social values which are connected with single-parent family households is studied based on statistical surveys. This work elaborates changes in number and structure of single-parent family households in Czech and Slovak Republic since 1970 till present. The first part outlines the view of experts on a broad concept of family and the family cycle. The next part evaluates the long-term evolution of marriage, divorce, fertility and changes in society values. The changes in society values are correlated with formation, structure and number of single parent family households in the Czech Republic and the Slovak Republic before and after 1990.

Abstract:
This chapter treats two fictional versions—histoires galantes—of the story of Ovid’s life: Madame de Villedieu’s Les Exilez de la cour d’Auguste (1672–8) and Anne de la Roche-Guilhen’s Histoire des Favorites (1697). It develops two main arguments: first that Ovid’s sociable love poetry, and his avowed use of a pseudonym for his mistress, made him appeal to a female-orientated literary culture and à clé reading and writing practices. To support this, it briefly explores uses of the figure of Ovid in works of other women writers. Second, it suggests that the mystery at the heart of Ovid’s exile allowed both Villedieu and La Roche-Guilhen to offer an imagined version of what happened to the court poet, which entails exploration of the boundaries between history and fiction and the processes behind official historiography. This, in turn, allowed both writers to reflect on the genre of the histoire galante.

Celestial mechanics abounds in interesting and counter-intuitive phenomena, such as descriptions of mass transfer between stars or optimal placements of satellites within the Solar System. Remarkably, many such features are already present in the restricted three-body problem, whose assumptions still allow for analytical understanding, and to which the second chapter is devoted. This ‘simplified’ system is discussed first in terms of forces (both gravitational and fictitious), and then using the Hamiltonian form. As well as traditional topics like stable and unstable Lagrange points and Roche lobes, a brief introduction to chaotic orbits is given. Additionally, readers are guided towards exploring on their own with numerical orbit integration.

Abstract:
This chapter details events in Josephine Roche's life from 1919 to 1927. For several years after the war, Roche remained an itinerant reformer. In part, she moved around a lot because she had not yet situated herself at what she considered a fundamental site for rectifying inequalities; she was as a result never quite satisfied with where she was. In addition, during the decade after the war, unlike any other time in her life, Roche's days were significantly shaped by the family claim. On July 2, 1920, Roche married Edward Hale Bierstadt after a whirlwind romance. Like many other members of the second generation of college-educated women, Roche expected to combine her public career with marriage, and her belief in the possibility of doing so was fueled by her political community.
