Zeta Canis Majoris

Zeta Canis Majoris (ζ Canis Majoris, abbreviated Zeta CMa, ζ CMa), also named Furud , is a spectroscopic binary in the constellation of Canis Major.
Name.
"Zeta Canis Majoris" is the star's Bayer designation assigned by the German astronomer Johann Bayer in 1603. 
The traditional name "Furud" or "Phurud" derives from the Arabic ألفرود "al-furūd" "the solitary ones". This was an appellation early Arab poets used for a number of anonymous stars. Later Arabian astronomers attempted to identify the name with particular stars, principally in the modern constellations Centaurus and Colomba. The stars of Colomba were assigned to Canis Majoris in the "Almagest", leading to more recent assignment of the name for Zeta Canis Majoris.
Al Sufi referred to these stars as ألأغربة "al-ʼaghribah" "the ravens".
In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN; which included "Furud" for this star.
Characteristics.
This star system has an apparent visual magnitude of +3.0, making it one of the brighter stars in the constellation and hence readily visible to the naked eye. Parallax measurements from the Hipparcos mission yield a distance estimate of around from the Sun. This is a single-lined spectroscopic binary system, which means that the pair have not been individually resolved with a telescope, but the gravitational perturbations of an unseen astrometric companion can be discerned by shifts in the spectrum of the primary caused by the Doppler effect. The pair orbit around their common center of mass once every 675 days with an eccentricity of 0.57.
The primary component is a large star with nearly four times the Sun's radius and almost eight times the mass of the Sun. It has a stellar classification of B2.5 V, which means it is a B-type main sequence star that is generating energy through the nuclear fusion of hydrogen at its core. It is emitting 3,603 times the luminosity of the Sun and is a suspected Beta Cephei variable. This energy is being radiated from its outer envelope at an effective temperature of about 18,700 K, giving it the blue-white hue of a B-type star. It is relatively young for a star, with an estimated age of 32 million years.
Zeta Canis Majoris is located close to the solar antapex.
