High mass star example
WebApr 11, 2024 · For example, we saw that the most massive main-sequence stars are the most luminous ones. We know of a few extreme stars that are a million times more luminous than the Sun, with masses that exceed 100 times the Sun’s mass. WebHigh mass stars go through a similar process to low mass stars in the beginning, except that it all happens much faster. They have a hydrogen fusion core, but much of the hydrogen …

WebAfter the initial “formation” of the galaxy, the higher mass stars in the first generation evolve more rapidly than the lower mass stars. For example, the evolutionary timescale for a 100 M⊙ star is only a few million years, while that for a 1 M⊙ star is nearly 10 billion years. WebLifespans for main sequence stars have a vast range. Whilst our Sun will spend 10 billion years on the main sequence, a high-mass, ten solar-mass (10M Sun) star will only last 20 million years (2.0× 10 7 years) on the main sequence. A star with a only half the mass of Sun can spend 80 billion years on the main sequence.
WebThe post-main sequence evolution of high-mass stars Core collapse supernovae: type II For more information White dwarfs and the Chandrasekhar limit In our previous class, we saw how low-mass stars (like the Sun) evolve once they leave the main sequence: they move up the red-giant branch, undergo a core helium flash,
WebJan 4, 2016 · Example, A star fused hydrogen into helium and 2 helium atoms into carbon. Would it keep fusing until it hits the limit and store it inside only to be released as an explosion. ... This view is very simplistic because it ignores two important facets of the evolution of high-mass stars - mixing and mass loss. Massive stars probably lose the ... bolivian national parksWebJan 10, 2024 · A high-mass star (many times more massive than the Sun) goes through a similar, but a slightly different process.
