Binary star system in the constellation Vela
This article is about L Velorum. For l Velorum, see HD 79917.
HD 83058 has generally been considered to be a single star, but high-resolution spectra show it to be a double-lined spectroscopic binary. The two components have approximately the same spectral type. Line-profile variations have been detected which suggest that at least one component pulsates, as is common for stars of this spectral class.
HD 83058 was proposed as a runaway star from a supernova explosion. However, the discovery that it is a binary makes this unlikely.
