Simbad=HD+71129Epsilon Carinae (ε Car / ε Carinae) is a
star in theconstellation Carina. Atapparent magnitude +1.86 it is one of the brightest stars in the nighttime sky, but is not visible from thenorthern hemisphere .It is also known by the name Avior, but this is not a classical name. It was assigned to the star by
Her Majesty's Nautical Almanac Office in the late 1930s during the creation of The Air Almanac, a navigational almanac for theRoyal Air Force . Of the fifty-seven stars included in the new almanac, two had no classical names: epsilon Carinae andalpha Pavonis . The RAF insisted that all of the stars must have names, so new names were invented. Alpha Pavonis was named Peacock, for obvious reasons, whilst epsilon Carinae was called Avior. [Sadler, D.H.: "A Personal History of H.M. Nautical Almanac Office", page 46. Edited and privately published by Wilkins, G.A., 1993]Epsilon Carinae is a
binary star located 630light year s away from theEarth . The primary component is a dyingorange giant of spectral class K0 III, and the secondary is a hothydrogen -fusing blue dwarf of class B2 V. The stars regularlyeclipse each other, leading to brightness fluctuations on the order of 0.1 magnitudes.Notes
