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 ...
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
This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year (distance traveled by light in one Julian year; approximately 9.46 trillion kilometres).
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 ...
A team of researchers at the Space Telescope Science Institute recently found that Leo P formed stars early on but ... massive O-type star. Together, the blue stars and bubble are part of a dwarf ...
One of the most massive stars known is Eta Carinae, [151] which, with 100–150 times as much mass as the Sun, will have a lifespan of only several million years. Studies of the most massive open clusters suggests 150 M ☉ as a rough upper limit for stars in the current era of the universe. [ 152 ]
It is a type of massive star called a red supergiant. "Its estimated mass means it has lived for about 10 to 20 million years, and will soon die," van Loon said.
Earlier observations found that, if placed at the center of our solar system, the massive star Betelgeuse would stretch out beyond the orbit of Jupiter. This new study finds its body would only ...
