Abstract

Multiperiodicity has been recognized as an important aspect of β Canis Majoris-type variability ever since the intensive observations of the “classical” members of this group by Struve and his coworkers in the early 1950’s. About half the stars observed by Struve exhibited a radial-velocity variation whose period was several hours, but whose amplitude was modulated with a period of the order of days. This quickly became known as the “beat phenomenon,” and was interpreted as an interference between two nearly equal short periods.
