IX Carinae (IX Car) is a red supergiant and pulsating variable star of spectral type M2Iab in the constellation Carina. It is a member of the Carina OB1 association along the Carina Nebula. IX Carinae is a semiregular variable star, but its properties are poorly-defined. Different sources give its brightness range as magnitude 7.2 to 8.5. or 6.87 to 7.9. The International Variable Star Index finds a period of approximately 384 days from ASAS-3 and visual observations, but also gives a possible period of 108 days. Another analysis finds a primary period of 408±50 d and a longer secondary period of 4,400±2,000 d.

Это одна из крупнейших известных звёзд, радиус которой в 920 раз больше солнечного. Светимость звезды в 133 000 раз больше солнечной, а температура её поверхности составляет 3650 K. Является полуправильной переменной звездой, видимая звёздная величина которой изменяется в интервале от 7,2m до 8,5m.

has abstract	IX Carinae (IX Car) es una estrella variable en la constelación de Carina, la quilla del Navío Argos.De magnitud aparente media +7,45, es una estrella lejana que se encuentra a una distancia estimada de 1640 pársecs (5330 años luz).Al igual que RT Carinae, es miembro del cúmulo estelar . IX Carinae es una supergigante roja de tipo espectral M2I con una temperatura efectiva de 3650 K.Tiene un radio 920 veces más grande que el del Sol, lo que equivale a 4,2 UA; si estuviese en el centro de nuestro Sistema Solar, su superficie se extendería casi hasta la órbita de Júpiter.En el espectro visible su luminosidad es 35.000 veces superior a la del Sol pero su luminosidad bolométrica —considerando todas las longitudes de onda— alcanza las cifra de 133.000 veces la luminosidad solar.Pierde masa en forma de polvo a razón de 2,0 × 10-9 masas solares por año. Catalogada como una variable semirregular SRC —cuyo prototipo es la brillante μ Cephei—, el brillo de IX Carinae fluctúa entre magnitud +7,2 y +8,5.Se conocen dos períodos de oscilación, uno principal de 408 ± 50 días, y otro, más largo e impreciso, de 4400 ± 2000 días. (es) IX Carinae (IX Car) is a red supergiant and pulsating variable star of spectral type M2Iab in the constellation Carina. It is a member of the Carina OB1 association along the Carina Nebula. IX Carinae is a semiregular variable star, but its properties are poorly-defined. Different sources give its brightness range as magnitude 7.2 to 8.5. or 6.87 to 7.9. The International Variable Star Index finds a period of approximately 384 days from ASAS-3 and visual observations, but also gives a possible period of 108 days. Another analysis finds a primary period of 408±50 d and a longer secondary period of 4,400±2,000 d. The physical characteristics of IX Carinae are also only known approximately, partly because of an uncertain distance. The effective temperature is around 3,600 K, while its bolometric luminosity is between 34,000 L☉ and 134,000 L☉. It is one of the largest stars with a radius of approximately 566 R☉ (394,000,000 km; 2.63 au). If placed at the center of the Solar System, it would extend close to the orbit of the outer Asteroid Belt Jupiter. IX Carinae has been listed as a candidate supernova close enough to Earth that pre-collapse neutrinos could be detected, allowing for observations of the star to be made from before the supernova explosion.
