Velocity-Space Substructure Of The Local Galactic Halo From K And M Dwarfs And Subdwarfs In The Superblink And Gaia Catalogs

Abstract

We present a study of the kinematics of nearby (d ≲ 1.2 kpc) high-velocity K and M dwarfs and subdwarfs from the SUPERBLINK proper motion catalog (μ > 40 mas/yr), incorporating data from the second Gaia Data Release 2. All K and M stars were selected based on their GBP - GRP colors and absolute G magnitudes, and distances were calculated from Gaia parallaxes. We plot transverse velocities, vT, of stars in six different directions on the sky, to examine the distribution of local K and M stars in the (U, V, W) velocity space system. Our analysis suggests that the velocity space distribution of local thick disk and halo stars, much like the velocity-space distribution of disk stars, is inhomogeneous and shows the signature of at least one global "stream" consisting of stars drifting toward Galactic center.
