Abstract:
We present the complete spectroscopic analysis of 455 stars observed
within the Penn State - Torun Centre for Astronomy Planet Search
(PTPS) with the High Resolution Spectrograph of the 9.2m Hobby-Eberly
Telescope. We also present the total sample of 744 evolved stars of
the PTPS and discuss masses of stellar hosts in our and other surveys
devoted to evolved planetary systems.
Stellar atmospheric parameters were determined through a strictly
spectroscopic LTE analysis of equivalent widths of FeI and FeII lines.
Rotational velocities were obtained from fitting synthetic spectra.
Radial velocities were obtained from fitting a Gaussian function to
the cross-correlation function. We determined stellar masses, ages,
and luminosities with a Bayesian analysis of theoretical isochrones.
The radii were calculated either from derived masses and logg or from
Teff and luminosities.
Description:
We present basic atmospheric parameters (Teff, logg, vt and [Fe/H]),
rotation velocities and absolute radial velocities as well as
luminosities, masses, ages and radii for 402 stars (including 11
single-lined spectroscopic binaries), mostly subgiants and giants. For
272 of them we present parameters for the first time. For another 53
stars we present estimates of Teff and log g based on photometric
calibrations.
We also present basic properties of the complete list of 744 stars
that form the PTPS evolved stars sample. We examined stellar masses
for 1255 stars in five other planet searches and found some of them
likely to be significantly overestimated. Applying our uniformly
determined stellar masses we confirm the apparent increase of
companions masses for evolved stars, and we explain it, as well as
lack of close-in planets with limited effective radial velocity
precision for those stars due to activity.

Note on table2.dat: Table 2 erroneously includes 20 stars that were finally
adopted for detailed spectroscopic analysis (including 11 SB1s mentioned in
the text) and are listed in Table 1 as well. Consequently, the corrected
Table 2 contains 33 rather than 53 stars. They are 18 SB2 stars, 14 ones with
variable CCFs (possibly SB2) and one with a weak CCF.
