YETI follow-up observations of the T Tauri star CVSO30 with transit-like dips
R. Bischoff, St. Raetz, M. Fernández +13
The T Tauri star CVSO30, also known as PTFO8-8695, was studied intensively with ground based telescopes as well as with satellites over the last decade. It showed a variable light…
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…
Transit analysis of the CoRoT-5, CoRoT-8, CoRoT-12, CoRoT-18, CoRoT-20, and CoRoT-27 systems with combined ground- and space-based photometry
St. Raetz, A. M. Heras, M. Fernández +2
We have initiated a dedicated project to follow-up with ground-based photometry the transiting planets discovered by CoRoT in order to refine the orbital elements, constrain their…
Direct Imaging discovery of a second planet candidate around the possibly transiting planet host CVSO 30
T. O. B. Schmidt, R. Neuhäuser, C. Briceño +11
We surveyed the 25 Ori association for direct-imaging companions. This association has an age of only few million years. Among other targets, we observed CVSO 30, which has recentl…
WASP-14 b: Transit Timing analysis of 19 light curves
St. Raetz, G. Maciejewski, M. Seeliger +11
Although WASP-14 b is one of the most massive and densest exoplanets on a tight and eccentric orbit, it has never been a target of photometric follow-up monitoring or dedicated obs…
No variations in transit times for Qatar-1 b
G. Maciejewski, M. Fernández, F. J. Aceituno +11
The transiting hot Jupiter planet Qatar-1 b was presented to exhibit variations in transit times that could be of perturbative nature. A hot Jupiter with a planetary companion on a…
