Multi-band transit observations of the TrES-2b exoplanet
D. Mislis, S. Schroter, J. H. M. M. Schmitt +2
We present a new data set of transit observations of the TrES-2b exoplanet taken in spring 2009, using the 1.2m Oskar-Luhning telescope (OLT) of Hamburg Observatory and the 2.2m te…
51 Pegasi - a planet-bearing Maunder minimum candidate
K. Poppenhaeger, J. Robrade, J. H. M. M. Schmitt +1
We observed 51 Peg, the first detected planet-bearing star, in a 55 ks XMM-Newton pointing and in 5 ks pointings each with Chandra HRC-I and ACIS-S. The star has a very low count r…
Detection of orbital parameter changes in the TrES-2 exoplanet ?
D. Mislis, J. H. M. M. Schmitt
We report a possible change in the orbit parameters of the TrES-2 exoplanet. With a period of 2.470621 days, the TrES-2 exoplanet exhibits almost "grazing" transits 110.4 minutes d…
Long-term stability of spotted regions and the activity-induced Rossiter-McLaughlin effect on V889 Herculis. A synergy of photometry, radial velocity measurements, and Doppler imaging
K. F. Huber, U. Wolter, S. Czesla +4
The young active G-dwarf star V889 Herculis (HD 171488) shows pronounced spots in Doppler images as well as large variations in photometry and radial velocity (RV) measurements. Ho…
