Abstract

Context.Since 1999, we have been conducting a radial velocity survey of 179 K giants using the Coudé Auxiliary Telescope at UCO/Lick observatory. At present ~20-100 measurements have been collected per star with a precision of 5 to 8 m s-1. Of the stars monitored, 145 (80%) show radial velocity (RV) variations at a level >20 m s-1, of which 43 exhibit significant periodicities.
