These massive stars don’t live very long, only a few million years (which is a very short amount of time compared to the billions of years it takes a galaxy to form). But while they’re alive, they emit a large amount of light, ... WebIn stars around the mass of the Sun, this begins at the tip of the red giant branch with a helium flash from a degenerate helium core, and the star moves to the horizontal branch where it burns helium in its core. More massive stars ignite helium in their core without a flash and execute a blue loop before reaching the asymptotic giant branch.

Web11 apr. 2024 · Massive stars evolve in much the same way that the Sun does (but always more quickly)—up to the formation of a carbon-oxygen core. One difference is that for stars with more than about twice the mass of the Sun, helium begins fusion more gradually, rather than with a sudden flash. WebThey evolve from large main-sequence stars. Supergiants can contain 8 - 200 times the mass of the Sun! They also shine brightly. One supergiant can be as bright as a million Suns. The colour of supergiants can be red or blue.

"WebDeath of a star. All stars eventually run out of their hydrogen gas fuel and die. The way a star dies depends on how much matter it contains—its mass. As the hydrogen runs out, a star with a similar mass to our sun will expand and become a red giant. When a high-mass star has no hydrogen left to burn, it expands and becomes a red supergiant.
