or even less. In the process, when it begins to run out of fuel in its core, it swells into a Red Supergiant. Then, when it finally reaches the end of its life, it tears itself apart in a colossal explosion known as a supernova. Betelgeuse...

red supergiant (redirected fromRed supergiants) n. A massive star of great size and luminosity that has a relatively low surface temperature ranging from 3,000 to 4,000 kelvin (4,940° to 5,740° F), giving it a reddish or orange hue. ...

This is also the first time astronomers were able to measure the size of a dying star in the early universe. This was based on the supernova’s brightness and rate of cooling, both of which depend on the size of the progenitor star. Hubble observations show that the re...
Massive stars becoming red supergiants lose a significant amount of their mass during that brief evolutionary phase. They then either explode as a hydrogen-rich supernova (SN Type II), or continue to evolve as a hotter supergiant (before exploding). The slow, dusty ejecta of the red ...

Here we report the instant multiband observations of a type II supernova (SN 2023ixf) in the galaxy M101 (at a distance of 6.85 ± 0.15 Mpc; ref. 8), beginning at about 1.4 h after the explosion. The exploding star was a red supergiant with a radius of about 440 ...
More precisely, whenever, at the pre-supernova stage, the H-rich envelope contains more than about 5\\\% of the initial mass, the star is a red supergiant, and whenever the H-rich envelope contains less than 1\\\% of the total mass the star is a blue supergiant. For intermediate si...
