Photometry of three Herbig Be stars - HD 53367, HD 200775, and HD 259431

E. M. Halbedel

Abstract

Four seasons of photometry for three premain-sequence Herbig Be stars (HD 53367, HD 200775, and HD 259431) are presented. Only one star (HD 53367) has been found to be optically variable, having uniformly declined in V magnitude and decreased in (B-V) over that time period. H-alpha spectra are discussed for HD 53367 and HD 200775.
