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 … Web8 okt. 2014 · • A Red Giant forms from a sun-like star. The star would go through nuclear fusion reactions that consumes almost all the hydrogen in the star’s core and turns it into helium. • The core will collapse till the fusion begins in a hot, gaseous shell around the core. • Energy caused from this fusion will make the star quickly expand to a large scale.

Giant stars have radii up …
Web20 apr. 2024 · The term hypergiant stars describe a star's luminosity rather than its physical size, so blue hypergiants can actually be smaller than the standard red giants formed by normal Sun-like stars towards the end of their lives, despite being many times brighter. Rare red hypergiants, however, are the biggest stars in the universe. Web11 jun. 2024 · A red giant star is formed when a star, like our Sun, burns all of its hydrogen and helium supplies.

WebThe End Of The Sun. The Helium Flash. The beginning of the end for a red giant the mass of our Sun occurs very suddenly. As the helium "ashes" continue to pile up at its center, a higher fraction of them turn electron-degenerate. It is an odd paradox: even as the outer layers of a red giant star are expanding into a huge but tenuous cloud, its ...
WebThe s-process is believed to be extensive in Red Giant stars of mass 3 − 8 M⊙ and to last for about 10 My, a short period in the total lifetime of a star. As the star proceeds through the s-process stage we can expect that the fusion reactions decrease while the gravitational contraction of the star continues. poverty in the philippines adbWebLower-mass stars will evolve into red giants and eventually white dwarfs, while more massive stars will become supergiants, explode as supernovae, and leave behind neutron stars or black holes. _ 4.
