The star is named Eta Carinae
and it is pegged to have a mass (in its early days) equivalent to that of 150 suns.
Scientists, according to (https://phys.org/news/2019-07-hubble-captures-cosmic-fireworks-ultraviolet.html) Phys Org , say that Eta Carinae
underwent a cataclysmic outburst called the Great Eruption in 1838.
NEW ANALYSIS OF THE MASSIVE Eta Carinae
star system supports the idea that the system once had three stars--but only two survived.
That's how fast material from a 170 year old stellar eruption sped away from the unstable, eruptive, and extremely massive star Eta Carinae
NASA MISSION/ETA CARINAE: Eta Carinae
is a binary system containing the most luminous and massive star within 10,000 light-years.
But here's the truth: if you were looking out of a starship's window in the midst of the Eta Carinae
Nebula, it would look not like its dazzling Hubble panorama but about as it looks in a richest-field telescope under a rural sky.
The brightest star, located in the northern part of the nebula, is the mysterious eta Carinae
, one of the most massive and luminous stellar systems known in the Galaxy.
The most famous example is Eta Carinae
, a star 7,500 light-years from Earth which, for a brief time in the mid-1800s, unleashed into space a shell of gas 10 times the mass of the sun and became the second-brightest star in the night sky.
The Carina Nebula is some 7500 lightyears from Earth and hosts some of the most massive and luminous stars in our Galaxy, including double-star system eta Carinae
, which boasts over 100 times the mass of our Sun.
Papers address high-mass star formation by gravitational collapse of massive cores, the binarity of Eta Carinae
, metallicity-dependent Wolf-Rayet winds, and an overview of cosmic infrared background and Population III, among other topics.
Instead of Alpha Orionis, Eta Carinae
, or Alpha Centauri they say Alpha Orion, Eta Carina, and (presumably) Alpha Centaurus.
