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.

海山二 （英語： Eta Carinae，簡寫為 η Car）是位于 船底座 的一個恆星系統（赤經 10 h 45.1 m、 赤緯 −59°41m），距離 太陽 7,500至8,000 光年，在北緯27°以北的地區难以看見，而在南緯30°是一顆 拱極星。 這個系統至少有兩顆恆星，其中一顆是位於恆星生命早期階段，質量大約是太陽150倍的 高光度藍變星 （LBV），並且至少已經流失30個 太陽質量。 雖然它被認為還有一顆較大的伴星，質量約為太陽30倍的 沃夫–瑞葉星 環繞著它，但海山二周圍有巨大厚重的紅色星 …

2022年4月19日 · This video, boasting over 47,000 views as of April 11th, explores the intense brightening seen in the 1840s and, using data from Hubble, Chandra, and Spitzer, explores in 3D the complex nested structures of gas and dust that were expelled in that event. Eta Carinae is a prime example of the outbursts in the dying stages of very high mass stars.

2015年1月6日 · Eta Carinae, the most luminous and massive stellar system within 10,000 light-years of Earth, is known for its surprising behavior, erupting twice in the 19th Explore Search

1996年6月10日 · Eta Carinae was the site of a giant outburst about 150 years ago, when it became one of the brightest stars in the southern sky. Though the star released as much visible light as a supernova explosion, it survived the outburst. Somehow, the explosion produced two polar lobes and a large thin equatorial disk, all moving outward at about 1.5 ...

2020年9月3日 · Astronomers aren’t certain, but one candidate is in Eta Carinae, a volatile system containing two massive stars that closely orbit each other. This image has three types of light: optical data from Hubble (appearing as white), ultraviolet (cyan) from Hubble, and X-rays from Chandra (appearing as purple emission).

2014年8月26日 · The Eta Carinae star system does not lack for superlatives. Not only does it contain one of the biggest and brightest stars in our galaxy, weighing at least 90 times the mass of the sun, it is also extremely volatile and is expected …

2020年2月4日 · Eta Carinae, formally known as Eta Argus, is a stellar system consisting of at least 2 stars located in the constellation of Carina. This star system’s luminosity is more than 5 million times greater than our Sun. Eta Carinae is the …
