Refining Parameters of the XO-5 Planetary System with High-Precision Transit Photometry
G. Maciejewski, M. Seeliger, Ch. Adam +2
Studies of transiting extrasolar planets offer an unique opportunity to get to know the internal structure of those worlds. The transiting exoplanet XO-5 b was found to have an ano…
Constraints on a second planet in the WASP-3 system
G. Maciejewski, A. Niedzielski, A. Wolszczan +30
There have been previous hints that the transiting planet WASP-3 b is accompanied by a second planet in a nearby orbit, based on small deviations from strict periodicity of the obs…
YETI observations of the young transiting planet candidate CVSO 30 b
St. Raetz, T. O. B. Schmidt, S. Czesla +32
CVSO 30 is a unique young low-mass system, because, for the first time, a close-in transiting and a wide directly imaged planet candidates are found around a common host star. The…
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…
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…
Analysis of new high-precision transit light curves of WASP-10 b: starspot occultations, small planetary radius, and high metallicity
G. Maciejewski, St. Raetz, N. Nettelmann +4
The WASP-10 planetary system is intriguing because different values of radius have been reported for its transiting exoplanet. The host star exhibits activity in terms of photometr…
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…
The Hercules-Lyra Association revisited New age estimation and multiplicity study
T. Eisenbeiss, M. Ammler-von Eiff, T. Roell +5
The Her-Lyr assoc., a nearby young MG, contains a few tens of ZAMS stars of SpT F to M. The existence and the properties of the Her-Lyr assoc. are controversial and discussed in th…
Towards the Rosetta Stone of planet formation
G. Maciejewski, R. Neuhaeuser, R. Errmann +18
Transiting exoplanets (TEPs) observed just about 10 Myrs after formation of their host systems may serve as the Rosetta Stone for planet formation theories. They would give strong…
Transit timing variation in exoplanet WASP-3b
G. Maciejewski, D. Dimitrov, R. Neuhaeuser +7
Photometric follow-ups of transiting exoplanets may lead to discoveries of additional, less massive bodies in extrasolar systems. This is possible by detecting and then analysing v…
Search for transiting exoplanets and variable stars in the open cluster NGC 7243
Z. Garai, T. Pribulla, L. Hambálek +23
We report results of the first five observing campaigns for the open stellar cluster NGC 7243 in the frame of project Young Exoplanet Transit Initiative (YETI). The project focuses…
