CoRoT-18 b: Analysis of high-precision transit light curves with starspot features

St. Raetz, A. M. Heras, P. Gondoin +4

When a planet occults a spotty area on a stellar surface, the flux increases and a characteristic feature in a light curve - a bump - is observed. Among the planets detected by the…

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 coronagraphic search for wide sub-stellar companions among members of the Ursa Major moving group

M. Ammler-von Eiff, A. Bedalov, C. Kranhold +4

We present the results of a survey to detect low-mass companions of UMa group members, carried out in 2003-2006 with NACO at the ESO VLT. While many extra-solar planets and planeta…

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…

Ground-based transit observations of the HAT-P-18, HAT-P-19, HAT-P-27/WASP-40 and WASP-21 systems

M. Seeliger, M. Kitze, R. Errmann +46

As part of our ongoing effort to investigate transit timing variations (TTVs) of known exoplanets, we monitored transits of the four exoplanets HAT-P-18b, HAT-P-19b, HAT-P-27b/WASP…

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…
