Mirzam is a blue-white giant star located at around 490 light-years away. Beta Canis Minoris (β Canis Minoris, abbreviated Beta CMi, β CMi), also named Gomeisa /ɡɒˈmaɪzə/,[12][13] is a star in the constellation of Canis Minor. β Canis Minoris (Latinised to Beta Canis Minoris) is the star's Bayer designation. Mirzam – β Canis Majoris (Beta Canis Majoris) Mirzam (Al-Murzim, Murzim) is a blue-white giant with brightness varying between magnitude 1.95 and 2.00. It is the 46th brightest star in the night sky. As such, it belongs to a class called slowly pulsating B-type (SPB) stars. The nature of the companion is unknown, but it is speculated that it could be a subdwarf O star remaining after binary interactions that spun up the Be primary. [17] Consequently, β Canis Minoris itself is known as 南河二 (Nán Hé èr, English: the Second Star of South River. β Canis Majoris (Murzim o Mirzam), con magnitud 1,98 es una estrella gigante azul y variable del tipo Beta Cephei. [19] An 'e' classification indicates that the spectrum contains emission lines, which means this is a Be star that is surrounded by a thin, circumstellar disk made of gaseous material ejected from the star. Von Mitteleuropa aus steht der Große Hund im Winter tief über dem Südhorizont. The WGSN's first bulletin of July 2016[16] included a table of the first two batches of names approved by the WGSN; which included Gomeisa for this star.

O nome vem do árabe مرزم que significa arauto. Beta Canis Majoris (β CMa, β Canis Majoris) is a star in the southern constellation of Canis Major, the 'greater dog', and is located at a distance of about 500 light-years (150 parsecs) from the Earth. Mirzam é uma gigante azul-branca de classe espectral B1 II-III. α Canis Majoris (), la estrella más brillante vista desde la Tierra con magnitud-1,46.Es orbitada, con un período de 50 años, por una enana blanca llamada Sirio B primero observada por Alvan Clark. Beta Canis Majoris The Bayer designation of the fourth-brightest star in the constellation Canis Major. The Sun's radius is 695,800km, therefore the star's radius is an estimated 11,757,558.14.km. Beta Canis Minoris has about 3.5 times the Sun's mass and is rotating rapidly with a projected rotational velocity of 210 km s−1,[9] which gives a lower bound on the azimuthal rotational velocity along the star's equator. Lynds, C. R. Abstract The star HD 21803 shows a variation in light of approximately 0.1 mag., with a period of approximately one-fifth of a day. Tau Canis Majoris estimated radius has been calculated as being 16.90 times bigger than the Sun. If confirmed, this would make it a member of the very rare Phi Persei Be+sdO type systems.[22].

Murzim (také Mirzam, Murzam, β Canis Majoris, β CMa) je hvězda v souhvězdí Velkého psa vzdálená od Země asi 490 světelných let.Tato hvězda představuje hlavu psa. With an average apparent magnitude of 1.985, it is the fourth brightest star in Canis Major, after Sirius, Adhara, and Wezen. [3], β Canis Minoris has long been suspected of variability,[20] and in 1977 it was classified as a γ Cassiopeiae variable in the General Catalogue of Variable Stars. Delta Canis Majoris (Latinised from δ Canis Majoris, abbreviated Delta CMa, δ CMa), officially named Wezen / ˈ w iː z ən /, is a star in the constellation of Canis Major.It is a yellow-white F-type supergiant with an apparent magnitude of +1.83. Mirzam is a Beta Cephei variable star that varies in magnitude between +1.97 and +2.01 over a six-hour period. Be stars that show these types of pulsation have been dubbed SPBe stars. [14], The stellar classification of this star is B8 Ve. )[18], From parallax measurements, the distance to this star is about 160 Â± 10 light-years (49.1 Â± 3.1 parsecs). The actual rotation rate may be about once per day. Beta Canis Majoris är belägen nära den bortre änden av den lokala bubblan, en kavitet i det lokala interstellära medium genom vilket solen rör sig. The companion would have about 42% of the Sun's mass. of +1.83. Le système solaire est situé dans un de ses deux lobes, l'autre lobe est centré au voisinage de l' étoile β Canis Majoris (Murzim). This hot, gaseous disk is about three times the radius of the star.
