AI Velorum star

An AI Velorum star is a type of pulsating variable that is very similar to a Delta Scuti star but has a greater amplitude (up to about 1.2 magnitude) and a period of 1 to 5 hours. The prototype, located in the constellation Vela, 2.8° north-northeast of Gamma Velorum, is the brightest of its class, with a magnitude range of 6.4 to 7.1. AI Velorum stars were formerly known as dwarf Cepheids.
