Abstract

Searches for planets around massive stars are essential for developing general understanding of planet formation and evolution of planetary systems. The main objective of the PSU-TCfA Search for Planets around Evolved Stars is detection of planets around G-K subgiants and giants through highly accurate radial velocity (RV) measurements using an iodine absorption cell on the HET HRS spectrograph. However, the long-period radial velocity variations of red giants may also have other causes than planets (e.g. non-radial pulsations or rotational modulation in the presence of starspots). In this work, for the second red giant with planets found in our survey, HD 102272, we present bisector analysis of cross-correlation functions (CCF) constructed from the spectra used for radial velocity determination but cleaned from the iodine lines.
