Long-Term Photometry of IC 348 with the YETI Network

D. J. Fritzewski, M. Kitze, M. Mugrauer +29

We present long-term photometric observations of the young open cluster IC 348 with a baseline time-scale of 2.4 yr. Our study was conducted with several telescopes from the Young…

On the GJ 436 planetary system

G. Maciejewski, A. Niedzielski, G. Nowak +4

The GJ 436 system contains a transiting planet GJ 436 b which is a hot analogue of Neptune on an eccentric orbit. Recently, two additional transiting sub-Earth planets have been po…

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…
