Probable new halo stars toward L = 360 deg, B = +30 deg
The Stock objective-prism radial-velocity survey catalog has beensearched for probable halo giants at intermediate Galactic longitude. Atotal of 83 objects were found. The sample yielded a velocity dispersionof 98 + or - 8 km/sec and a frequency of 0.15 halo giants brighter thanm(pg) = 11.5/sq deg.
| Southern stars of high radial velocity
First, it has been shown that the Stock Velocity Survey is a usefulsource of velocity information on 8-13th mag southern stars. Theparticular use has been to identify stars of very large velocity.Thackeray (1975) has tabulated those galactic objects with heliocentricradial velocities over 250 km/s; his list contains 69 objects, of which59 are stellar. The authors have found twelve more stars. Second, theslit spectra of a sample of high-velocity stars in the Stock Surveyrevealed several extremely metal-weak stars. Abundance analysis forthese objects would be worthwhile. Finally, among the high-velocityobjects are a surprising number of late B and early A stars. In mostinstances, these objects appear to be spectroscopically normal,main-sequence stars, but three are definite A + G spectrum binaries.High-velocity binaries are rare.
