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…

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…

A Possible Detection of Occultation by a Proto-planetary Clump in GM Cephei

The YETI Collaboration, W. P. Chen, S. C. -L. Hu +41

GM Cep in the young (~4 Myr) open cluster Trumpler 37 has been known to be an abrupt variable and to have a circumstellar disk with very active accretion. Our monitoring observatio…

A new flare star member candidate in the Pleiades cluster

M. Moualla, T. O. B. Schmidt, R. Neuhäuser +19

We present a new flare star, which was discovered during our survey on a selected field at the edge of the Pleiades cluster. The field was observed in the period 2007 - 2010 with t…

Young Exoplanet Transit Initiative (YETI)

R. Neuhäuser, R. Errmann, A. Berndt +80

We present the Young Exoplanet Transit Initiative (YETI), in which we use several 0.2 to 2.6m telescopes around the world to monitor continuously young (< 100 Myr), nearby (< 1 kpc…

The nearby eclipsing stellar system delta Velorum. II. First reliable orbit for the eclipsing pair

T. Pribulla, A. Merand, P. Kervella +8

Context. The nearby multiple system delta Velorum contains a widely detached eclipsing binary and a third component. Aims. We take advantage of this system offering the opportunity…
