Mirzam
Beta Canis Majoris
Names For This Star
Other names for this star ar Murzim or Mirza. The names derive from the Arabic name Al Murzim, "The Announcer."
The name may refer to the fact that Mirzam is situated to the east of Sirius, which is the brightest star of the nighttime sky. Thus Mirzam rises before that star. So the rising of Mirzam prefigures or announces the rising of Sirius
Description of the Star

Beta Canis Majoris is the prototype star for a certain class of oscillating, variable stars characterized by a multiplicity of periods. Burnham says that there is relation between period and luminosity as with the better known Cepheid variables.
The principle period of oscillation for Mirzam is about 6 hours.
