Metal-poor stars uvby-beta photometry. XI.
Listed in IVOA Registry (Virtual Observatory)
New uvby-beta data are provided for 442 high-velocity and metal-poor stars; 90 of these stars have been observed previously by us, and 352 are new.
Description
When combined with our previous two photometric catalogues, the data base is now made up of 1533 high-velocity and metal-poor stars, all with photometry and complete kinematic data. Hipparcos, plus a new photometric calibration for M_v_ also based on the Hipparcos parallaxes, provide distances for nearly all of these stars; our previous photometric calibrations give values for E(b-y) and [Fe/H].
The [Fe/H],V(rot) diagram allows us to separate these stars into different Galactic stellar population groups, such as old-thin-disk, thick-disk, and halo. The X histogram, where X is our stellar-population discriminator combining V(rot) and [Fe/H], and contour plots for the [Fe/H],V(rot) diagram both indicate two probable components to the thick disk.
