Five-colour photometry of 12 magnetic variable stars.
Abstract
A discussion is presented of photo-electric five-colour observations of 12 magnetic variable stars made in 1966. The periods of these variables range from to 314d From four stars no photometric observations have been reported as yet, viz. HD 15144, HD 188041, HD 190073 and HD 221760. The light- and colour-curves are given and their ranges are schematically represented in three colour-colour diagrams. Most of the colour changes are more or less parallel to the main sequence, but only for a small number of stars is this parallelity present in all three colour-colour diagrams. Key words: magnetic variable stars-photometry
