Four-colour and H BET photometry of southern B stars at high galacticlatitudes.
Abstract
Four-color and H beta photometry has been obtained for 105 early-type HD stars with galactic latitudes less than -45 deg. They are mostly late B stars of luminosity class V to III. Two new Am stars and several Ap or Bp stars are detected photometrically. Absolute magnitudes are determined from the photometry and from MK types where available. The interstellar reddening of many of the more distant stars is very small, suggesting either the existence of undetected peculiar stars in the sample or that there are areas of effectively zero reddening at high southern galactic latitudes.
