Such as for instance Regulus, Denebola are an unexpected rotator, which leads to an oblate shape of the brand new superstar, having a fat from the equator. Brand new star’s projected rotational acceleration is actually 128 kilometer/s.
Denebola including exhibits a powerful infrared continuously, which suggests so it may have an excellent circumstellar particles computer regarding dirt in orbit.
Brand new star is one of the IC 2391 supercluster, an exceptional organization whoever representative stars display a common activity because of room, however they are maybe not gravitationally sure. Almost every other superstars that belong to that particular association is actually Alpha Pictoris in new constellation Pictor, Beta Canis Minoris on constellation Canis Minor, while the celebs in the great outdoors https://www.datingranking.net/tr/kik-inceleme/ group IC 2391, labeled as the new Omicron Velorum Cluster, located in the constellation Vela.
