Web8 de set. de 2024 · Red supergiants start off as main-sequence stars that carry a mass between 8 and 40 solar masses. These stars burn hydrogen in their cores and can take up to 20 million years to complete this. This hydrogen will then remain present around the core (which is now made from helium), resulting in a further expansion into supergiants. WebRed 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-AGB stars. WebStephenson 2 DFK 1 (abbreviated to RSGC2-01), also known as Stephenson 2-18 (abbreviated to St2-18), is an enigmatic red supergiant (RSG) or possible extreme red hypergiant (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 … how does protein come from dna
