UBV beta Database for Case-Hamburg Northern and Southern Luminous Stars
A database of photoelectric UBV beta photometry for stars listed in theCase-Hamburg northern and southern Milky Way luminous stars surveys hasbeen compiled from the original research literature. Consisting of over16,000 observations of some 7300 stars from over 500 sources, thisdatabase constitutes the most complete compilation of such photometryavailable for intrinsically luminous stars around the Galactic plane.Over 5000 stars listed in the Case-Hamburg surveys still lackfundamental photometric data.

Evolution of intermediate mass stars - The role of convective overshooting and stellar wind
The evolution of Pop I intermediate mass stars is followed from thezero-age main sequence until the early AGB in the presence of convectiveovershooting from the central cores and mass loss by stellar wind inlate stages. Use is made of the determination of Kettner et al. (1982)for the C-12 (alpha, gamma) O-16 reaction rate. Several importantconsequences are shown to be possible if substantial overshooting occursin the convective cores of real stars. The new evolutionary models havemuch larger convective cores and therefore larger He and CO cores thanthe classical ones. The evolutionary tracks in the H-R diagram run athigher luminosities, and cover a wider range of effective temperaturesduring the core H-burning phase. However, the extension of the blueloops during the core H-burning phase is strongly reduced. Finally, themass limits which confine intermediate stars are significantly loweredby the effect of overshooting on critical masses for nondegenerative Heand C ignition.

Estimation of spectral classifications for bright southern stars with interesting Stromgren indices
This paper investigates the degree of success with which uvby photometrycan be applied to predict spectral classifications for 947 A, F, and Gstars brighter than an apparent magnitude of 8.3 and with four-colorindices indicating some kind of interesting, unusual, or peculiarspectrum. One or several possible spectral classifications are estimatedfor each star from photometry alone, double stars are distinguished, andthe estimates are compared with published classifications. The resultsshow that the framework provided by uvby photometry can be extended toinclude most G and K stars, reddened stars, peculiar stars, and certaintypes of double star.
