Abstract:
For the past 3 years we have been monitoring 62 K giant stars using
precise stellar radial velocity (RV) measurements with the 2m Alfred
Jensch Telescope of the Thuringer Landessternwarte Tautenburg (TLS).
To probe the dependence of planet formation on stellar mass by finding
planets around intermediate-mass giant stars.
We present high accuracy RV measurements of the K1.5 III star 42 Dra
and the K4 III star HD 139357. The wavelength reference for the RV
measurements was provided by an iodine absorption cell placed in the
optical path of the spectrograph.
Description:
42 Dra and HD 139 357 belong to a star sample observed since February
2004 from the Thuringer Landessternwarte Tautenburg (TLS) as part of
the Tautenburg Observatory Planet Search Programme (TOPS).
