New High Proper Motion Stars from the Digitized Sky Survey. III. Stars with Proper Motions 0."45 < μ < 2."0 yr⁻¹South of Declination -30°

We report the discovery of 182 southern stars with proper motion larger than 0 45 yr -1 . The stars were found in an expansion of the SUPERBLINK proper-motion survey to 8980 deg 2 south of decl. = -30°. The new high proper motion stars include 123 objects with μ > 0 5 yr -1 and 5 with μ > 1 0 yr -1 . These newfound stars consist of a variety of nearby red dwarfs and white dwarfs and (slightly more distant) red halo subdwarfs, and they are all prime targets for follow-up spectroscopic and astrometric (parallax) observations. Comparison with previous proper-motion surveys in the southern sky suggests that SUPERBLINK has a recovery rate between 80% and 90% at southern declinations for stars with red magnitude 10 mag < R F < 19 mag and proper motion in the range 0 5 < μ < 2 0 yr -1 . This survey makes a significant addition to the census of high proper motion stars at southern declinations.
