In exoplanetary science it is essential to determine the planetary parameters with the highest possible precision. These parameters are important for our understanding of the nature of the exoplanets and serve as input parameters for the scientific studies which follow.
The French satellite mission CoRoT delivers qualitative high photometric signals of around 100,000 stars and has lead to 17 confirmed planets up to now. The evaluation of the data for these planets has, until now been mostly achieved using a rather non-homogeneous setup in terms of staff, software versions, expertise etc.
Therefore, a homogeneous study of all currently known CoRoT planets is desirable. Such a study should ideally be performed by one software in the most possible homogeneous way including all knowledge, e. g., gained during evaluation of the confirmed planets, and new aspects such as improved handling of limb darkening, binning and reflection effects. Another outcome of studying the transit events of a planet is the measurement of a possible transit timing variation. These variations can provide hints for other companions in the examined system.
"This work focuses on the spectral classification of variable stars. These stars were observed with BEST II from March to September 2010 and were followed up by spectroscopy done with AAOmega in February 2012. The spectral classification is done by comparing the observed spectra with a grid of synthetic spectra created with SME (Spectroscopy Made Easy) using cross-correlation and a chi square fit. The goal is to gain a better understanding of binary star evolution."
"Die Wechselwirkungen zwischen Klimavariablen und der biogenen Aktivität von Mikroorganismen unter Anwendung eines eindimensionalen gekoppelten Klima-Photochemiemodells, welches wiederum an einen biogeochemischen Kreislauf koppelt, sollen untersucht werden. Es werden sowohl Szenarien für (a) erdähnliche extrasolare Planeten, die in der habitablen Zone um M-Zwergsterne kreisen, als auch im Vergleich dazu die (b) frühe Erde modelliert."
