Abstract (from CDS):
We report the discovery of 152 new high proper motion systems (µ≥0".4/yr) in the southern sky (δ=-47° to 00°) brighter than UKST plate R59F=16.5 via our SuperCOSMOS-RECONS (SCR) search. This paper complements Paper XII in the Solar Neighborhood series, which covered the region from δ=-90° to -47° and discussed all 147 new systems from the southernmost phase of the search. Among the total of 299 systems from both papers, there are 148 (71 in Paper XII, 77 in this paper) new systems moving faster than 0".5/yr that are additions to the classic Luyten Half Second sample. These constitute an 8% increase in the sample of all stellar systems with µ≥0".5/yr in the southern sky. As in Paper XII, distance estimates are provided for the systems reported here based on a combination of photographic plate magnitudes and Two Micron All Sky Survey photometry, assuming that all stars are on the main sequence. Two SCR systems from the portion of the sky included in this paper are anticipated to be within 10 pc, and an additional 23 are within 25 pc. In total, the results presented in Paper XII and here for this SCR sweep of the entire southern sky include five new systems within 10 pc and 38 more between 10 and 25 pc. The largest number of nearby systems have been found in the slowest proper motion bin, 0".6/yr>µ≥0".4/yr, indicating that there may be a large population of low proper motion systems very near the Sun.
