High-Resolution Spectroscopy of the Transiting Planet Host Star TrES-1

Sozzetti, A; Yong, David; Torres, G; Charbonneau, D; Latham, D.W.; Prieto, Carlos Allende


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, log g = 4.6 ± 0.2, and [Fe/H] = 0.00 ± 0.09. By measuring the Ca II activity indicator and by putting useful upper limits on the Li abundance, we constrain the age of TrES-1 to be 2.5 ± 1.5 Gyr. By comparing theoretical stellar...[Show more]
