Overview. Although red supergiants are often considered the largest stars, some other star types have been found to temporarily increase significantly in radius, such as during LBV eruptions or luminous red novae. Luminous red novae appear to expand extremely rapidly, reaching thousands to tens of thousands of solar radii within only a few ...
A few notable large stars with masses less than 60 M☉ are shown in the table below for the purpose of comparison, ending with the Sun, which is very close, but would otherwise be too small to be included in the list. At present, all the listed stars are naked-eye visible and relatively nearby. Star name. Location.
UY Scuti(BD-12°5055) is a red supergiantstar, located 5,900 light-yearsaway in the constellation Scutum. It is also a pulsating variable star, with a maximum brightness of magnitude8.29 and a minimum of magnitude 10.56, which is too dim for naked-eyevisibility.
R136a1. A near-infrared image of the R136 cluster. R136a1 is at the center with R136a2 close by, R136a3 below right, and R136b to the left. 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.
VY Canis Majoris. VY Canis Majoris (abbreviated to VY CMa) is an extreme oxygen-rich red hypergiant or red supergiant (O-rich RHG or RSG) and pulsating variable star 1.2 kiloparsecs (3,900 light-years) from the Solar System in the slightly southern constellation of Canis Major.
WOH G64 ( IRAS 04553-6825) is an unusual [3] red supergiant (RSG) star in the Large Magellanic Cloud (LMC) satellite galaxy in the southern constellation of Dorado. It is the largest known star whose radius has been verified.
Red supergiants ( RSGs) are stars with a supergiant luminosity class ( Yerkes class I) and a stellar classification K or M. [1] They are the largest stars in the universe in terms of volume, although they are not the most massive or luminous. Betelgeuse and Antares A are the brightest and best known red supergiants (RSGs), indeed the only first ...
Stephenson 2 DFK 1, also known as RSGC2-01 [a] or St2-18, is a red supergiant (RSG) or possible extreme red hypergiant [2] (RHG) star in the constellation of Scutum.It lies near the open cluster Stephenson 2, which is located about 5.8 kiloparsecs (19,000 light-years) away from Earth in the Scutum–Centaurus Arm of the Milky Way galaxy, and is assumed to be one of a group of stars at a ...
