- W Canis Majoris (W CMa) is a carbon star in the constellation Canis Major. A cool star, it has a surface temperature of around 2,900 K and a radius 234 times that of the Sun, with a bolometric absolute magnitude of −4.13 and distance estimated at 443 or 445 parsecs (1,444–1,450 light-years) based on bolometric magnitude or radius. The Gaia Data Release 2 parallax of 1.8049±0.1454 milliarcseconds implies a distance of about 555 parsecs. W CMa is classified as a slow irregular variable star. Detailed analyses have found only very weak and probably spurious periods of approximately a month. It is a carbon star, an asymptotic giant branch star where carbon and s-process elements have been dredged up to the surface during thermal pulses of the helium-burning shell. (en)
- W Canis Majoris är en halvregelbunden variabel av SR-typ i stjärnbilden Stora hunden. Stjärnan varierar mellan magnitud +6,27 och 7,09 (fotografisk magnitud) med en period av 160 dygn. (sv)
- W Большого Пса (лат. W Canis Majoris), HD 54361 — одиночная переменная звезда в созвездии Большого Пса на расстоянии приблизительно 1807 световых лет (около 554 парсеков) от Солнца. Видимая звёздная величина звезды — от +6,98m до +6,39m. (ru)
