A New Spectroscopic and Photometric Analysis of the Transiting Planet Systems TrES-3 and TrES-4
A. Sozzetti, G. Torres, D. Charbonneau +17
We report new spectroscopic and photometric observations of the parent stars of the recently discovered transiting planets TrES-3 and TrES-4. A detailed abundance analysis based on…
Rotation and Macroturbulence in Metal-poor Field Red Giant and Red Horizontal Branch Stars
Bruce W. Carney, David F. Gray, David Yong +4
We report the results for rotational velocities, Vrot sin i, and macroturbulence dispersion, zeta(RT), for 12 metal-poor field red giant branch stars and 7 metal-poor field red hor…
Observational Tests of Planet Formation Models
A. Sozzetti, G. Torres, D. W. Latham +8
We summarize the results of two experiments to address important issues related to the correlation between planet frequencies and properties and the metallicity of the hosts. Our r…
Line Broadening in Field Metal-poor Red Giant and Red Horizontal Branch Stars
Bruce W. Carney, David W. Latham, R. P. Stefanik +1
We report 349 radial velocities for 45 metal-poor field red giant and red horizontal branch stars. We have have identified one new spectroscopic binary, HD 4306, and one possible s…
Improving Stellar and Planetary Parameters of Transiting Planet Systems: The Case of TrES-2
A. Sozzetti, G. Torres, D. Charbonneau +5
We report on a spectroscopic determination of the atmospheric parameters and chemical abundance of the parent star of the recently discovered transiting planet {TrES-2}. A detailed…
A Keck/HIRES Doppler Search for Planets Orbiting Metal-Poor Dwarfs. I. Testing Giant Planet Formation and Migration Scenarios
A. Sozzetti, G. Torres, D. W. Latham +5
We describe a high-precision Doppler search for giant planets orbiting a well-defined sample of metal-poor dwarfs in the field. This experiment constitutes a fundamental test of th…
