The PennState/Toru\'n Center for Astronomy Search for Planets Around Evolved Stars. Basic parameters of a sample of evolved stars

摘要

The objective of the PSU/TCfA Search for Planets Around Evolved Stars is tostudy evolution of planetary systems in the stellar evolution timescale. Forsuch an analysis precise physical parameters of the hosts of the planetarysystems are essential. In this paper we present an attempt to obtain basicphysical parameters for a sample of evolved stars observed within our surveywith the High Resolution Spectrograph of the Hobby-Eberly Telescope.
