A study of the activity of G and K giants through their precise radial velocity. Breaking the 10-m/sec accuracy with FEROS. [link]Paper  abstract   bibtex   
Asteroseismology is an indispensable tool that uses the properties of stellar oscillations to probe the internal structure of stars. This can provide a direct test of stellar structure and evolution theory. Precise stellar radial velocity (RV) measurements made in recent years have not only discovered the first extra-solar planets, but have also uncovered new classes of low-amplitude variable stars. One such is represented by the K giant stars which exhibit RV variations with amplitudes in the range of 50-300 m/s (Walker et al. 1989, Hatzes & Cochran 1993,1994 ab). This variability is multi-periodic and occurring on two time- scales: less than 10 days and several hundreds of days.
