A Keck/HIRES Doppler Search for Planets Orbiting Metal-Poor Dwarfs
A. Sozzetti, D. W. Latham, G. Torres +4
We present results from our ongoing spectroscopic search for giant planets within 1 AU around a well-defined sample of metal-poor stars with HIRES on the Keck 1 telescope. We have…
High-Resolution Spectroscopy of the Transiting Planet Host Star TrES-1
A. Sozzetti, D. Yong, G. Torres +6
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 ir…
TrES-1: The Transiting Planet of a Bright K0V Star
Roi Alonso, Timothy M. Brown, Guillermo Torres +9
We report the detection of a transiting Jupiter-sized planet orbiting a relatively bright (V=11.79) K0V star. We detected the transit light-curve signature in the course of the TrE…
On the Possible Correlation Between the Orbital Periods of Extra-solar Planets and the Metallicity of the Host Stars
A. Sozzetti
We investigate a possible correlation between the orbital periods of the extra-solar planet sample and the metallicity [Fe/H] of their parent stars. Close-in planets, on a few-…
