Some red supergiants undergo blue loops where they temporarily increase in temperature before returning to the red supergiant state. This depends on the mass, rate of rotation, and chemical makeup of the star. While many red supergiants will not experience a blue loop, some can have several. Temperatures can reach 10,000K at the peak of the ...
Red giants include stars in a number of distinct evolutionary phases of their lives: a main red-giant branch (RGB); a red horizontal branch or red clump; the asymptotic giant branch (AGB), although AGB stars are often large enough and luminous enough to get classified as supergiants; and sometimes other large cool stars such as immediate post ...
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.
UY Scuti (BD-12°5055) is a red supergiant star, located 5,900 light-years away in the constellation Scutum.It is also a pulsating variable star, with a maximum brightness of magnitude 8.29 and a minimum of magnitude 10.56, which is too dim for naked-eye visibility.
Rigel, the brightest star in the constellation Orion is a typical blue-white supergiant; the three stars of Orion's Belt are all blue supergiants; Deneb is the brightest star in Cygnus, another blue supergiant; and Delta Cephei (itself the prototype) and Polaris are Cepheid variables and yellow supergiants.
K to M type spectra, the largest known stars by radius. Hypergiant luminosity classes are rarely applied to red supergiants, although the term red hypergiant is sometimes applied to the most extended and unstable red supergiants, with radii on the order of 1,000 to 2,000 R ☉.
Damian Lillard is the only one going supernova these days. The Hubble Space Telescope revealed why nearby red giant star Betelgeuse became surprisingly dim late last year, according to a new study.
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 ...
