Betelgeuse is a red supergiant that has evolved from an O-type main-sequence star. After core hydrogen exhaustion, Betelgeuse evolved into a blue supergiant before evolving into its current red supergiant form. [98] Its core will eventually collapse, producing a supernova explosion and leaving behind a compact remnant. The details depend on the ...
Those red supergiants such as Betelgeuse that do have modest rates of rotation may have acquired it after reaching the red supergiant stage, perhaps through binary interaction. The cores of red supergiants are still rotating and the differential rotation rate can be very large. [21]
Betelgeuse having a binary counterpart would explain some of its perceived patterns of brightness. ... a second star wouldn’t be atypical for a red supergiant like Betelgeuse, and could explain ...
In late 2019 and early 2020, Betelgeuse blew its top. Literally. Around that time the famous bright star marking the right shoulder of Orion suddenly started dimming, dropping to about half its ...
A red supergiant star orbited by a smaller B-type main-sequence star with a radius estimated between 13 [49] and 25 R ☉. [50] Widely recognised as being among the largest known stars. [19] Another estimate give a radius of 660 R ☉ [23] based on the Gaia DR3 distance of 1 kpc. [31] U Lacertae A 1,013 [23] L/T eff: KW Sagittarii: 1,009 ± 142 ...
This red giant star will, one day, explode as a supernova. Betelgeuse is one of the best-known stars in the night sky, as well as the easiest to find. New examinations of this behemoth star ...
Betelgeuse is a red supergiant star about 700 light-years away that serves as the shoulder in the Orion constellation, according to NASA. Given its intense luminosity, Betelgeuse is what ...
Betelgeuse is a red supergiant star in the Orion constellation. ... Betelgeuse, oil tanker destroyed in the 1979 Whiddy Island Disaster, Ireland; USS ...
