Several X-ray and gamma ray sources have been detected around η Carinae, for example 4U 1037–60 in the 4th Uhuru catalogue and 1044–59 in the HEAO-2 catalog. The earliest detection of X-rays in the η Carinae region was from the Terrier-Sandhawk rocket, [66] followed by Ariel 5, [67] OSO 8, [68] and Uhuru [69] sightings.
The Cosmic Cliffs at the edge of NGC 3324, one of the first images taken by the James Webb Space Telescope. The Carina Nebula [7] or Eta Carinae Nebula [8] (catalogued as NGC 3372; also known as the Great Carina Nebula [9]) is a large, complex area of bright and dark nebulosity in the constellation Carina, located in the Carina–Sagittarius Arm of the Milky Way galaxy.
Several X-ray and gamma-ray sources have been detected around Eta Carinae, for example 4U 1037–60 in the 4th Uhuru catalogue and 1044–59 in the HEAO-2 catalog. The earliest detection of X-rays in the Eta Carinae region was from the Terrier-Sandhawk rocket, [ 60 ] followed by Ariel 5 , [ 61 ] OSO 8 , [ 62 ] and Uhuru [ 63 ] sightings.
Luminous blue variable stars can undergo "giant outbursts" with dramatically increased mass loss and luminosity. η Carinae is the prototypical example, [20] with P Cygni showing one or more similar outbursts 300–400 years ago, [21] but dozens have now been catalogued in external galaxies.
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. It also includes another massive and luminous star, HD 93129A. It is approximately 2,680 parsecs (8,700 ly) from Earth. [3]
Possible examples of supernova impostors include the Great Eruption of Eta Carinae, P Cygni, SN 1961V, [3] SN 1954J, SN 1997bs, SN 2008S in NGC 6946, and SN 2010dn [1] where detections of the surviving progenitor stars are claimed.
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.
AG Carinae, a massive Luminous blue variable and a part of the Carina constellation, which is transitioning from an O-type star to a Wolf-Rayet star. Eta Carinae, inside the Carina Nebula in the southern constellation of Carina. Eta Carinae is extremely massive, possibly as much as 120 to 150 times the mass of the Sun, and is four to five ...
