HD 96919 [SEP] constellation
HD 96919
HD 96919, also known by its Bayer designation of z Carinae and the variable star designation of V371 Carinae, is a blue supergiant star in the constellation Carina. It lies near the Carina Nebula and at a comparable distance.
V371 Car is an α Cyg variable, erratically pulsating and changing brightness by a few hundredths of a magnitude. Periods of 10 - 80 days have been identified. It shows unusual emission lines in its spectrum, and high-velocity absorption (HVA) events, temporary spectral features
that are thought to indicate localised regions of enhanced mass loss.
HD 96919 is a B9 supergiant, possibly located 6,000 light years from Earth. It is considered to be a post red supergiant star, either evolving towards a Wolf-Rayet star or on a blue loop before returning to a cooler temperature.
