Avior (Epsilon Carinae)
Artistic rendering of the Avior binary system (Epsilon Carinae).
Avior (Epsilon Carinae) is the third brightest star in the constellation Carina. Avior is a spectroscopic binary consisting of a main sequence B star and a giant K star, separated by just 0.02 arcseconds. There is some evidence that the components eclipse each other, producing a slight drop in brightness every 2.2 years; if so, this suggests a separation distance of about 4 astronomical units (AU) – less than the distance of Jupiter from the Sun, but too far apart for mass transfer to take place.
