New high-proper motion survey in the Southern sky Scholz R.-D., Irwin M., Ibata R., Jahreiss H., Malkov O.Yu. <Astron. Astrophys. 353, 958 (2000)> =2000A&A...353..958S
ADC_Keywords: Proper motions ; Stars, high-velocity ; Magnitudes Keywords: astrometry - stars: kinematics - stars: low-mass, brown dwarfs - stars: white dwarfs Abstract: We present the discovery of about 100 new high-proper motion stars in the region between 0h and 7h in right ascension and -63° and -32° in declination, with proper motions between 0.3 and 1.0arcsec/yr. In addition we have obtained improved coordinates and photographic photometry for another about 100 already known high-proper motion stars in the same region. In this study we have made use of APM measurements of UKST survey plates in 40 survey fields. Using all available information (position, proper motion, photographic R magnitude and BJ-R colour index), we draw some preliminary conclusions on the nature of the new high-proper motion stars, particularly of extreme cases.

For the cool WDs if DA then the less Balmer lines the cooler the type, however, it is impossible to tell the difference between DC and DA WDs for our faint WDs at the given signal-to-noise and resolution. Most of the WDs should have 5000∼K to 6000∼K)
