  • EV Carinae est une étoile supergéante rouge et une variable pulsante de type spectral M4Ia dans la constellation de la Carène. Elle est un membre probable de l'association stellaire (en) le long de la nébuleuse de la Carène, à une distance présumée de ∼8 000 a.l. (∼2 450 pc) environ. EV Car est une étoile variable semi-régulière dont la magnitude apparente visuelle varie de 7,4 à 9,0, ce qui fait qu'elle ne peut être vue qu'avec des jumelles ou un télescope. Différentes périodes ont été identifiées, mais celle qui domine est d'environ 347 jours. (fr)
