RR Lyr: kinematics, orbits and z-distribution
Listed in IVOA Registry (Virtual Observatory)
RR Lyrae stars in the Milky Way are good tracers to study the kinematic behaviour and spatial distribution of older stellar populations.
Description
A recently established well documented sample of 217 RR Lyr stars with V<12.5mag, for which accurate distances and radial velocities as well as proper motions from the Hipparcos and Tycho-2 catalogues are available, has been used to reinvestigate these structural parameters. The kinematic parameters allowed to calculate the orbits of the stars.
Nearly 1/3 of the stars of our sample have orbits staying near the Milky Way plane.
