New high proper motion stars (-90<DE< -47)

DOI

We report the discovery of 141 new high proper motion systems ({mu}>=0.4"/yr) in the southern sky (DE=-90 to -47{deg}) brighter than UKST plate R_59F_=16.5 via our SuperCOSMOS-RECONS search. When combined with the nine systems having {mu}>=1.0"/yr and/or late spectral type from the initial phases of this effort, we find that 73 of the 150 total systems are moving faster than 0.5"/yr and are therefore new members of the classic Luyten Half-Second sample. These constitute a 21% increase in the sample of stars with {mu}>=0.5"/yr in the declination region searched, thereby comprising an important addition to this long-neglected region of the sky. Distance estimates are provided for the entire sample, based on a combination of photographic plate magnitudes and Two Micron All Sky Survey photometry, using the relations recently presented by Hambly et al. for the presumed main-sequence stars. Three systems are anticipated to be within 10pc, and an additional 15 are within 25pc. Nine of these 18 nearby systems have proper motions falling between 0.4"/yr and 0.6"/yr, hinting at a large population of nearby stars with fast, but not extremely high, proper motions that have not been thoroughly investigated.
