Absolute stellar photometry in the region 1900–3000 Å

  • J. W. Campbell

Abstract

Twin channel stellar photometers were flown in two sounding rockets in May 1967 and produced a number of absolute photoelectric measurements in the region 2000–3000 Å.

The observations were made at wavelengths centred on 2150 Å and 2550 Å with passbands of 300 Å on 28 early-type stars in the range of spectral types B0-B9.5 down to a limiting visual magnitude of 4.8.

A comparison of the experimental data with other observations and with the theoretically derived fluxes of Mihalas for unblanketed models, indicates a satisfactory agreement within the limits of the known photometric accuracies, although there are significant departures for those stars exhibiting emission characteristics and for the magnetic variable α2 Canum Venaticorum.
