Contribution

It provides new physical parameters for a sample of evolved stars, crucial for studying planetary system evolution during stellar aging.

Findings

Physical parameters for the sample stars were successfully determined.

The data supports analysis of planetary system evolution around evolved stars.

Enhanced understanding of stellar evolution stages in the context of exoplanet studies.

Abstract

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