Oscillations in Procyon A: First results from a multi-site campaign
S. Hekker, T. Arentoft, H. Kjeldsen +45
Procyon A is a bright F5IV star in a binary system. Although the distance, mass and angular diameter of this star are all known with high precision, the exact evolutionary state is…
Discovery of a planet around the K giant star 4 UMa
M. P. Doellinger, A. P. Hatzes, L. Pasquini +4
Context: For the past 3 years we have been monitoring a sample of 62 K giant stars using precise stellar radial velocity measurements taken at the Thueringer Landessternwarte Taute…
Confirmation of the Planet Hypothesis for the Long-period Radial Velocity Variations of Beta Geminorum
A. P. Hatzes, W. D. Cochran, M. Endl E. W. Guenther +6
We present precise stellar radial velocity measurements for the K giant star Beta Gem spanning over 25 years. These data show that the long period low amplitude radial velocity var…
Planets of young stars: the TLS radial velocity survey
M. Esposito, E. Guenther, A. P. Hatzes +1
We report on the search for planets orbiting 46 nearby young stars performed at the State Observatory of Turingia (TLS) by means of a radial velocity survey. The aim of this progra…
