HD 93129A
HD 93129A is a hot O class star in the Carina Nebula. It is one of the most luminous stars in the Milky Way.〔 It is the dominant member of the Trumpler 14 star cluster, a young star cluster within the Carina OB1 stellar association that harbors other super luminous stars, like Eta Carinae and WR 25.
HD 93129A has a close neighbour within Trumpler 14, an O3.5 main-sequence star (HD 93129B) 3 arc-seconds away. In addition, HD 93129A itself has recently been found to be a close binary, with the fainter companion being yet another very hot O3.5V. The components have been resolved, but their separation has decreased from 55 mas in 2004 and only 27 mas in 2013. Luminosity data is still quoted here for the two stars combined. A further 5 fainter stars within 5 arc-seconds have been detected.〔
