J/AJ/134/1579       Halo stars in solar neighborhood     (Kepley+, 2007)

Halo star streams in the solar neighborhood. Kepley A.A., Morrison H.L., Helmi A., Kinman T.D., Van Duyne J., Martin J.C., Harding P., Norris J.E., Freeman K.C. <Astron. J., 134, 1579-1595 (2007)> =2007AJ....134.1579K

Our sample (231 stars) includes red giants, RR Lyrae variable stars, and red horizontal branch stars within 2.5kpc of the Sun with [Fe/H] less than -1.0. It was chosen to include stars with accurate distances, space velocities, and metallicities, as well as well-quantified errors. With our data set, we confirm the existence of the streams found by Helmi and coworkers (1999Natur.402...53H), which we refer to as the H99 streams. File Summary:
