The companion candidate near Fomalhaut - a background neutron star?
Ralph Neuhaeuser, Markus Hohle, Christian Ginski +3
The directly detected planetary mass companion candidate close to the young, nearby star Fomalhaut is a subject of intense discussion. While the detection of common proper motion l…
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…
The Vela Pulsar With an Active Fallback Disk
Gökçe Özsükan, K. Yavuz Ekşi, Valeri Hambaryan +4
Fallback disks are expected to form around young neutron stars. The presence of these disks can be revealed by their blackbody spectrum in the infrared, optical and UV bands. We pr…
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…
Superflares on the slowly rotating solar-type stars KIC10524994 and KIC07133671?
M. Kitze, R. Neuhäuser, V. Hambaryan +1
An investigation of the G-type stellar population with Kepler (as done by Maehara et al.) shows that less than 1 per cent of those stars show superflares. Due to the large pixel sc…
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…
