Abstract:
We transformed radial velocities compiled from more than 1400
published sources, including the Geneva-Copenhagen survey of the solar
neighborhood (2004, Nordstrom et al., Cat. V/117), into a uniform
system based on the radial velocities of 854 standard stars in our
list (Gontcharov, 2006, Cat. III/252 ). This enabled us to calculate
the average weighted radial velocities for more than 25000 HIPPARCOS
stars located in the local Galactic spiral arm (Orion arm) with a
median error of 1km/s. We use these radial velocities together with
the stars coordinates, parallaxes, and proper motions to determine
their Galactic coordinates and space velocities. These quantities,
along with other parameters of the stars, are available from the
continuously updated Orion Spiral Arm CAtalogue (OSACA) and the
associated database. We perform a kinematic analysis of the stars by
applying an Ogorodnikov-Milne model to the OSACA data. The kinematics
of the nearest single and multiple main-sequence stars differ
substantially.
