The aim of this thesis is to understand if cyanobacteria, grown on an Earth-like planet orbiting around the habitable zone of an M star can survive and use the light coming from the star in a fruitful way, in particular analyzing their gaseous by-products. The organisms chosen usually don't have photopigments capable to photosynthesize the NIR part of the radiation, but can modify their photosynthetic apparatus in order to adapt to different light conditions if exposed in NIR light conditions, producing chlorophyll d and f. The two bacteria highlighted for our purpose are Chlorogloeopsis frits

The ice giants, Uranus and Neptune, are the two outermost planets in our solar system. With only one satellite flyby each in the late 1980’s, the ice giants are arguably the least understood of the planets orbiting the Sun. A better understanding of these planets’ atmospheres will not only help satisfy the natural scientific curiosity we have about these distant spheres of gas, but also might provide insight into the dynamics and meteorology of our own planet’s atmosphere. Two new ground-based, near-infrared datasets of the ice giants are studied. Both datasets provide data in a portion of the

Ensemble calculations for the period from 2000 to 2010 were carried out with the middle and upper atmosphere model (MUAM), and an analysis of the quarterdiurnal tide is performed. The global temporal and latitudinal distributions of the quarterdiurnal tide are modeled with MUAM, and their forcing mechanisms are examined. The quarterdiurnal tides show a similar distribution over the year in the northern and southern hemisphere, with maxima of the amplitude in late winter and spring as well as in autumn. In the latitude-height distribution is also shown that the largest amplitudes of the quarter

Recently, an increasing number of modelling and observational studies have looked at the signatures of small-scale waves, such as gravity waves (GWs) of meteorological origin, in the upper atmosphere. General circulation models require an appropriate GW parameterisation to reproduce a realistic global circulation. Existing schemes implemented into GCMs lack a physically proper wave dissipation mechanism above the turbopause. For more self-consistent wave propagation in GCMs, and to estimate their dynamic and energetic importance in the upper atmosphere, it is crucial to account for realistic u

A three-dimensional mechanistic model of the middle atmosphere is used to model various classes of equatorial wave motions that are observed in the atmosphere. These waves are thought to be largely responsible for the forcing of the quasi-biennial oscillation (QBO) in the tropical lower stratosphere. By generating a combination of different classes of equatorial waves in the model, an oscillation which has many similarities to the observed QBO is produced in the model. The numerical model used is run in a variety of configurations, including running it at different vertical resolutions and wit

We investigate the effect of wind clumping on the dynamics of Wolf-Rayet winds, by means of the Potsdam Wolf-Rayet (PoWR) hydrodynamic atmosphere models. In the limit of microclumping the radiative acceleration is generally enhanced. We examine the reasons for this effect and show that the resulting wind structure depends critically on the assumed radial dependence of the clumping factor D(r). The observed terminal wind velocities for WR stars imply that D(r) increases to very large values in the outer part of the wind, in agreement with the assumption of detached expanding shells.
