J/A+A/458/873  Stellar parameters of metal-rich solar-type stars  (Sousa+, 2006)

Spectroscopic parameters for a sample of metal-rich solar-type stars. Sousa S.G., Santos N.C., Israelian G., Mayor M., Monteiro M.J.P.F.G. <Astron. Astrophys. 458, 873 (2006)> =2006A&A...458..873S

To check for new correlations between stars and the existence of an orbiting planet, we determine accurate stellar parameters for several metal-rich solar-type stars. The purpose is to fill the gap of the comparison sample presented in previous works in the high metal-content regime. Description: Table 23 (tables 2 & 3 of the paper) contains the derived stellar parameters, metallicities, and masses, for stars not known to harbor any planetary-mass companion. Table 4 contains the derived stellar parameters, metallicities, and masses, for extra-solar planet-host stars. File Summary:
