J/A+A/384/879       Galactic orbits of stars with planets      (Barbieri+, 2002)

Galactic orbits of stars with planets Barbieri M., Gratton R.G. <Astron. Astrophys. 384, 879 (2002)> =2002A&A...384..879B
ADC_Keywords: Stars, ages ; Stars, masses ; Radial velocities ; Proper motions ; Abundances, [Fe/H] Keywords: stars: planetary systems - stars: abundances 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. File Summary:
