Abstract:
We have reconstructed the galactic orbits of the parent stars of
exoplanets. For comparison, we have recalculated the galactic orbits
of stars from the Edvardsson et al. (1993, Cat. <J/A+A/275/101>)
catalog. A comparison between the two samples indicates that stars
with planets are not kinematically peculiar. At each perigalactic
distance stars with planets have a metallicity systematically larger
than the average for the comparison sample. We argue that this result
favors scenarios where the presence of planets is the cause of the
higher metallicity of stars with planets.
Description:
File table1.dat contains the coordinates, radial velocity and proper
motion of stars with planets. File table2.dat contains physical
characteristic of stars with planets. File table4.dat contains data
about galactic orbits of stars with planets.
