Qatar-1: indications for possible transit timing variations
C. von Essen, S. Schröter, E. Agol +1
Variations in the timing of transiting exoplanets provide a powerful tool detecting additional planets in the system. Thus, the aim of this paper is to discuss the plausibility of…
A consistent analysis of three years of ground- and space-based photometry of TrES-2
S. Schröter, J. H. M. M. Schmitt, H. M. Müller
The G0V dwarf TrES-2A, which is transited by a hot Jupiter, is one of the main short-cadence targets of the Kepler telescope and, therefore, among the photometrically best-studied…
The high-energy environment in the super-earth system CoRoT-7
K. Poppenhaeger, S. Czesla, S. Schröter +3
High-energy irradiation of exoplanets has been identified to be a key influence on the stability of these planets' atmospheres. So far, irradiation-driven mass-loss has been observ…
The corona and companion of CoRoT-2A. Insights from X-rays and optical spectroscopy
S. Schröter, S. Czesla, U. Wolter +3
CoRoT-2 is one of the most unusual planetary systems known to date. Its host star is exceptionally active, showing a pronounced, regular pattern of optical variability caused by ma…
Multi-band transit observations of the TrES-2b exoplanet
D. Mislis, S. Schroter, J. H. M. M. Schmitt +2
We present a new data set of transit observations of the TrES-2b exoplanet taken in spring 2009, using the 1.2m Oskar-Luhning telescope (OLT) of Hamburg Observatory and the 2.2m te…
How stellar activity affects the size estimates of extrasolar planets
S. Czesla, K. F. Huber, U. Wolter +2
Lightcurves have long been used to study stellar activity and have more recently become a major tool in the field of exoplanet research. We discuss the various ways in which stella…
