UBV Observations of the RS CVn Binary HK Lacertae between 1978-1985

No. 91 (Vol. 10, Part 5)
Budapest, 1988

Abstract

We report 524 UBV observations of the RS CVn binary HK Lac made between 1978-1985. Our starspot modelling results published previously for 12 light curves (using V colour) are summarized. Three additional modelled light curves are presented which have not been published before. Nine UBV light and colour curves obtained between 1982-85 in 16 American and 2 Hungarian observatories, are given. Light curve modelling made for the V and B light curves separately show that the resulting model parameters agree well within the error of the modelling procedure.
