Stellar evolution - Wikipedia

https://en.wikipedia.org/wiki/Stellar_evolution

WebChart of stellar evolution. Stellar evolution is the process by which a star changes over the course of time. Depending on the mass of the star, its lifetime can range from a few million years for the most massive to trillions of years for the least massive, which is considerably longer than the current age of the universe.

WebStellar Evolution: A Journey with Chandra. The Milky Way galaxy contains several hundred billion stars of various ages, sizes and masses. A star forms when a dense cloud of gas collapses until nuclear reactions begin deep in the interior of the cloud and provide enough energy to halt the collapse. Many factors influence the rate of evolution ...

WebApr 11, 2022 · The numbers show how many years each star takes to become a giant after leaving the main sequence. The red line is the zero-age main sequence. Note that the most massive star in this diagram has a mass similar to that of Betelgeuse, and so its evolutionary track shows approximately the history of Betelgeuse.
