UvbyHbeta_ photometry of main sequence A type stars.
We present Stroemgren uvby and Hbeta_ photometry for a set of575 northern main sequence A type stars, most of them belonging to theHipparcos Input Catalogue, with V from 5mag to 10mag and with knownradial velocities. These observations enlarge the catalogue we began tocompile some years ago to more than 1500 stars. Our catalogue includeskinematic and astrophysical data for each star. Our future goal is toperform an accurate analysis of the kinematical behaviour of these starsin the solar neighbourhood.
| Walraven photometry of nearby southern OB associations
Homogeneous Walraven (VBLUW) photometry is presented for 5260 stars inthe regions of five nearby southern OB associations: Scorpio Centaurus(Sco OB2), Orion OB1, Canis Major OB1, Monoceros OB1, and Scutum OB2.Derived V and (B - V) in the Johnson system are included.
| Scanner K-line photometry of Orion stars
Results are presented for two-channel scanner measurements of calciumK-line strengths in 39 Orion sword and belt stars. Values of the calciumk index and its associated standard error are given for each observedstar, and the K-line strengths are compared with those of K-linestandard stars and Hyades stars. Plots of k index againstreddening-corrected color and of k-index deviation againstmetal-strength index deviation are provided which show that the Orionsword and belt stars do not differ significantly in their calcium andmetal abundances from general field stars.
