η Carinae (Eta Carinae, abbreviated to η Car), formerly known as η Argus, is a stellar system containing at least two stars with a combined luminosity greater than five million times that of the Sun, located around 7,500 light-years (2,300 parsecs) distant in the constellation Carina.
Detailed look on Eta Carinae. Carina Nebula (left), Homunculus Nebula (center), and high resolution image of Eta Carinae (right). [10] Each lobe has polar "hole" although it is not known whether it is an actual gap in the shell of the lobe or just a deep indentation. Surrounding each polar hole is a "trench".
Trumpler 16 (Tr 16) is a massive open cluster that is home to some of the most luminous stars in the Milky Way galaxy. It is situated within the Carina Nebula complex in the Carina–Sagittarius Arm, located approximately 9,270 ly (2,842 pc) from Earth. [1]
Carina OB1 is a giant OB association in the Carina Nebula, [1] which is home to some of the most massive and luminous stars in the Milky Way Galaxy. It includes the young star clusters Collinder 228 , NGC 3293 , NGC 3324 , IC 2581 , Trumpler 14 , Trumpler 15 and Trumpler 16 , [ 2 ] the last being the home of Eta Carinae .
The luminosity of Eta Carinae B is particularly uncertain, probably several hundred thousand L ☉ and almost certainly no more than 1 million L ☉. The most notable feature of Eta Carinae is its giant eruption or supernova impostor event, which originated in the primary star and was observed around 1843.
HD 93205, or V560 Carinae, is a binary stellar system, in the Carina Nebula (NGC 3372) in the constellation Carina. It consists of two massive O-stars that revolve around each other in 6 days . The more massive member of the pair is an O3.5 main sequence star.
HD 93129 is a triple star system in the Carina Nebula, with all three components being hot O class stars amongst 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.
[1] Supernova impostors are stellar explosions that appear at first to be a supernova but do not destroy their progenitor stars. As such, they are a class of extra-powerful novae. They are also known as Type V supernovae, Eta Carinae analogs, and giant eruptions of luminous blue variables (LBV). [2]
