Astrometric follow-up observations of directly imaged sub-stellar companions to young stars and brown dwarfs
C. Ginski, T. O. B. Schmidt, M. Mugrauer +4
The formation of massive planetary or brown dwarf companions at large projected separations from their host star is not yet well understood. In order to put constraints on formatio…
Transit timing of TrES-2: a combined analysis of ground- and space-based photometry
St. Raetz, G. Maciejewski, Ch. Ginski +21
Homogeneous observations and careful analysis of transit light curves can lead to the identification of transit timing variations (TTVs). TrES-2 is one of few exoplanets, which off…
Integrated optics interferometric four telescopes nuller
Ronny Errmann, Stefano Minardi, Lucas Labadie +3
Nulling interferometry has been identified as a competitive technique for the detection of extrasolar planets. The technique consists in combining out-of-phase pairs of telescopes…
Transit Timing Analysis in the HAT-P-32 system
M. Seeliger, D. Dimitrov, D. Kjurkchieva +24
We present the results of 45 transit observations obtained for the transiting exoplanet HAT-P-32b. The transits have been observed using several telescopes mainly throughout the YE…
The search for transiting planets using the YETI network
R. Errmann, St. Raetz, M. Kitze +2
To search for young transiting planets in continuous light curves, we monitor young open clusters (2-200 Myr) with the YETI network. Here we report the first transiting candidates…
Investigation of a transiting planet candidate in Trumpler 37: an astrophysical false positive eclipsing spectroscopic binary star
R. Errmann, G. Torres, T. O. B. Schmidt +50
We report our investigation of the first transiting planet candidate from the YETI project in the young (~4 Myr old) open cluster Trumpler 37. The transit-like signal detected in t…
