It is the most massive star that has a Bayer designation. It was only discovered to be (at least) two stars in the past few decades. Both the obscuring clouds and the great distances also make it difficult to judge whether the star is just a single supermassive object or, instead, a multiple star system. A number of the "stars" listed below may ...
R136a1 (short for RMC 136a1) is one of the most massive and luminous stars known, at nearly 200 M ☉ and nearly 4.7 million L ☉, and is also one of the hottest, at around 46,000 K. It is a Wolf–Rayet star at the center of R136 , the central concentration of stars of the large NGC 2070 open cluster in the Tarantula Nebula (30 Doradus ) in ...
A yellow hypergiant, one of the rarest types of stars. V838 Monocerotis: 464 [81] L/T eff: During the 2002 Red Nova, the star's radius may have increased up to 3,190 R ☉. [82] Pistol Star (V4647 Sagittarii) 420 [83] L/T eff: One of the most luminous stars known. La Superba (Y Canum Venaticorum) 344 [84] L/T eff: Mira (ο Ceti A) 332–402 [85] AD
The most massive type of degenerate star is the neutron star. See Most massive neutron star for this recordholder. [NB 3] Most massive neutron star PSR J0740+6620: 2019 2.14 M ☉ Several candidates exist which have a higher mass, however their mass has been measured by less precise methods and as such their mass value is regarded as less ...
Researchers estimate that it could contain somewhere between 1,000 and 10,000 trillion stars. Astronomers just discovered one of the most massive objects in the universe hiding behind the Milky ...
The James Webb Space Telescope has helped demystify the strange 2009 observation of a giant star about 25 times more massive than the sun that appeared to disappear from existence.
No, actually -- even NASA is calling this star the "loneliest" in the universe. "The unusual object, called CX330, was first detected as a source of X-ray light in 2009," according to a NASA news ...
O type main-sequence stars and the most massive of the B type blue-white stars become supergiants. Due to their extreme masses, they have short lifespans, between 30 million years and a few hundred thousand years. [30] They are mainly observed in young galactic structures such as open clusters, the arms of spiral galaxies, and in irregular ...
