Abstract:
To date, metallicity is the only parameter of a star that appears to
clearly correlate with the presence of planets and their properties.
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.
