High-Resolution Spectroscopy of the Transiting Planet Host Star TrES-1
We report on a spectroscopic determination of the stellar parameters and chemical abundances for the parent star of the transiting planet TrES-1. Based on a detailed analysis of iron lines in our Keck and Hobby-Eberly Telescope spectra, we derive Teff=5250+/-75 K, logg=4.6+/-0.2, and [Fe/H]=0.00+/-0.09. By measuring the Ca II activity indicator and
