Hβ line profile variability of seven southern Be stars

  • 1. Universidad Catolica de Chile, Santiago, (Chile)

Description

The results of spectroscopic observations of six B0-B4e and one B7e stars at the Manuel Foster Observatory (Chile) during 1984-87 are reported. By means of photographic spectroscopy (20 A/mm), equivalent widths, peak separations and V/R ratios were obtained for a total of 106 Hβ and 7 Hγ line profiles. Emission episodes in Hβ were detected in 27 CMa and λ Pav, lasting at least 5 months and 18 days respectively. Significant variations in the equivalent width of the Hβ emission line Wβ in time scales of months were found in κ CMa, PP Car and QY Car
