Discovery of the secondary eclipse of HAT-P-11 b
K. F. Huber, S. Czesla, J. H. M. M. Schmitt
We report the detection of the secondary eclipse of HAT-P-11 b, a Neptune-sized planet orbiting an active K4 dwarf. Using all available short-cadence data of the Kepler mission, we…
Glimpses of stellar surfaces. II. Origins of the photometric modulations and timing variations of KOI-1452
P. Ioannidis, J. H. M. M. Schmitt
The deviations of the mid-transit times of an exoplanet from a linear ephemeris are usually the result of gravitational interactions with other bodies in the system. However, these…
How do starspots influence the transit timing variations of exoplanets? Simulations of individual and consecutive transits
P. Ioannidis, K. F. Huber, J. H. M. M. Schmitt
Transit timing variations (TTVs) of exoplanets are normally interpreted as the consequence of gravitational interaction with additional bodies in the system. However, TTVs can also…
Kepler-210: An active star with at least two planets
P. Ioannidis, J. H. M. M. Schmitt, Ch. Avdellidou +2
We report the detection and characterization of two short-period, Neptune-sized planets around the active host star Kepler-210. The host star's parameters derived from those planet…
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…
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…
