Young, high-velocity stars. I - Rotational velocities and a catalog of early-type stars at the South Galactic Pole
A catalog has been compiled of 305 early-type stars to F0 and 15thmagnitude in 218 sq deg at the South Galactic Pole. Stromgren photometryand medium- and high-resolution spectra for many of the catalog starshave been obtained. Radial velocities, H-beta line widths, Balmer jumps,and Ca II K line equivalent widths have been measured and tabulated.Rotational velocities were obtained for eight distant A stars and arefound to be typical of values for normal young main sequence stars.

Young, high-velocity a stars. II - Misidentified, ejected, or unique?
The ages, abundances, and kinematics of a large number of early-typestars at the south Galactic pole are derived to examine the properties,augment the sample of high-velocity stars, and study hypothesesconcerning their origin. The results are compared to a group of normal Astars near the disk. It is suggested that at around 6.5 X 10 to the 8thyr ago, a major source of relatively low abundance hydrogen was accretedby the Galactic disk, forming young high-velocity stars that do notpartake of the age-abundance-kinematics relationships shown by otherstellar groupings.

Hyades and Sirius supercluster members brighter than magnitude(V) 7.1. I - The first six hours of right ascension
This is the first of four papers listing the probable members of theHyades and Sirius superclusters among stars brighter than V = 7.1 mag.The star sample is contained in the Bright Star Catalogue and itsSupplement, augmented with a further supplement of 550 stars foundduring various observing programs over the past 40 years. Accurate,four-color and H-beta, or (RI), photometry is available for most of thesupercluster members. The criteria for membership are the comparisons ofthe proper motion, radial velocity, and luminosity obtained from thesupercluster parameters with the observed motions and the luminosityderived from the photometric parameters. New proper motions, based onall available catalogs, have been derived for the additional 550 starsdiscussed here, as well as for all supercluster members.
