Abstract:
The aim of this paper is the revision and redocumentation of Ostrea (Gigantostrea) gigantica Solander var. oligoplana Sacco, 1897, Ostrea (Ostrea) isseli n. denom. Rovereto, 1897, and Ostrea (Ostrea) isseli n. denom. var. elongata Rovereto, 1897. These taxa are from the Oligocene strata of the Molare Formation (Tertiary Piedmont Basin, southern Piedmont - central Liguria, NW Italy). The syntypes of O. (G.) gigantica var. oligoplana are in the "Collezione Bellardi e Sacco", at the Museo Regionale di Scienze Naturali di Torino; the syntypes of O. (O.) isseli and O. (O.) isseli var. elongata are

Abstract:
In the last few years Asteroseismology has contributed to the knowledge of stellar interior, in some extend. This contribution has been done with -observations, providing the characteristics of the acuostic modes of stellar oscillations; and with theory relating them to inner parameters, locating stars in the JCD diagram (Christesen-Dalsgaard J., 1989). At the beginning only classical pulsating stars had high enough amplitudes able to be detected. But techniques have been improved and now the goal is the detection of oscillations in all kind of stars, specially solar-like ones. Up to now, few

Abstract:
As estrelas Subgigantes são estrelas que estão em um ramo pós-sequência principal e precedem o estágio das gigantes vermelhas. Nesse período evolutivo, as estrelas cessaram a fusão de hidrogênio no núcleo estelar, mas ainda não iniciaram a fusão do hélio no núcleo. Esse ramo evolutivo não é tão extenso quando comparado à sequência principal. Ao todo, encontramos 123 estrelas subgigantes binárias a partir de 1.274.059 de dados estelares observados em comum pelo GAIA e pelo Kepler; utilizamos os dados do DR2 disponíveis no gaia-kepler.fun. A partir desses dados, fizemos uma análise de excentrici

Tesis (Doctor en Astronomía)--Universidad Nacional de Córdoba, Facultad de Matemática, Astronomía y Física, 2015.<br>Actualmente es un hecho aceptado que las estrellas de secuencia principal que albergan planetas gigantes son, en promedio, más ricas en metales que aquéllas sin planetas detectados. Sin embargo, en el caso de las estrellas evolucionadas, especialmente las gigantes, los resultados han sido más dispares o controversiales por lo que el tema permanece abierto. Por otro lado, aún se debate fuertemente si las estrellas de secuencia principal con planetas gigantes poseen menor abundanc
