| dbo:abstract | V520 Carinae (en abrégé V520 Car) est une étoile variable de cinquième magnitude de la constellation australe de la Carène. Elle porte également la désignation de Bayer de w Carinae, V520 Carinae étant sa désignation d'étoile variable. D'après la mesure de sa parallaxe annuelle par le satellite Hipparcos, l'étoile est distante d'approximativement ∼1 140 a.l. (∼350 pc) de la Terre. Elle s'éloigne du Système solaire à une vitesse radiale de +9 km/s. Elle est un membre proposé du groupe mouvant d'étoiles d'IC 2391. V520 Carinae a été classée comme une étoile géante rouge de type spectral K4III par Houk & Cowley (1975), mais aussi comme une supergéante de K3Ib par Humphreys (1970). C'est une variable irrégulière à longue période et sa magnitude apparente varie entre 4,50 et 4,59 sans périodicité. Le rayon de l'étoile est actuellement 131 fois plus grand que le rayon solaire ; après avoir épuisé les réserves en hydrogène qui étaient contenues dans son noyau, elle s'est refroidie et étendue. Une comparaison de ses propriétés avec des trajectoires d'évolution théoriques suggèrent qu'elle est âgée de 33 millions d'années et que sa masse est 7,9 fois plus grande que celle du Soleil. L'étoile est environ 3 600 fois plus luminseuse que le Soleil et sa température de surface est de 3 903 K. (fr) V520 Carinae is a single star in the southern constellation of Carina. It has the Bayer designation w Carinae, while V520 Carinae is a variable star designation. The star has an orange hue and is faintly visible to the naked eye with an apparent visual magnitude that fluctuates around +4.58. It is located at a distance of approximately 1,140 light years from the Sun based on parallax, and it is drifting further away with a radial velocity of +9 km/s. It is a candidate member of the IC 2391 moving group of co-moving stars. This is an aging giant star with a stellar classification of K4III, although Humphreys (1970) found a supergiant class of K3Ib. It is a suspected slow irregular variable of type Lc and its brightness varies from magnitude +4.50 to +4.59 with no periodicity. The star now has 131 times the girth of the Sun, having exhausted the supply of hydrogen at its core then cooled and expanded. Comparison with theoretical evolutionary tracks suggests it is 33 million years old with 7.9 times the mass of the Sun, although analysis of its motion suggests it may be an astrometric binary with a mass of 1.014 M☉. The star is radiating 3,600 times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 3,903 K.
