Recent Photometric Behavior of the Unusual Be Star HD 45677 = FS Canis Majoris
Abstract
Four years of recent photometry for the unusual Be star HD 45677 = FS CMa is presented. The star is shown to vary actively during the time period observed. A quasi-periodicity of 296.5 days has been found for the recent data but does not entirely satisfy historical magnitudes. The feasibility of several models is discussed and a spectrum centered on H-alpha is presented.
