Motion Verified Red Stars (MoVeRS): A Catalog of Proper Motion Selected Low-mass Stars from WISE, SDSS, and 2MASS

TL;DR

The MoVeRS catalog provides a comprehensive list of over 8.7 million low-mass stars with verified proper motions, combining data from SDSS, 2MASS, and WISE to facilitate studies of stellar kinematics and low-mass star populations.

Contribution

This work introduces the first large-scale proper motion catalog of low-mass stars combining SDSS, 2MASS, and WISE data with a robust selection method.

Findings

Over 8.7 million low-mass stars cataloged.

Proper motions verified with >2σ significance.

Catalog accessible via SDSS CasJobs and VizieR.

Abstract

We present a photometric catalog of 8,735,004 proper motion selected low-mass stars (KML-spectral types) within the Sloan Digital Sky Survey (SDSS) footprint, from the combined SDSS Data Release 10 (DR10), Two-Micron All-Sky Survey (2MASS) Point Source Catalog (PSC), and Wide-field Infrared Survey Explorer (WISE) AllWISE catalog. Stars were selected using $r-i$, $i-z$, $r-z$, $z-J$, and $z-W1$ colors, and SDSS, WISE, and 2MASS astrometry was combined to compute proper motions. The resulting 3,518,150 stars were augmented with proper motions for 5,216,854 earlier type stars from the combined SDSS and United States Naval Observatory B1.0 catalog (USNO-B). We used SDSS+USNO-B proper motions to determine the best criteria for selecting a clean sample of stars. Only stars whose proper motions were greater than their $2$$\sigma$ uncertainty were included. Our Motion Verified Red Stars (MoVeRS) catalog is available through SDSS CasJobs and VizieR.
