Understanding diagrams of the late stages of stellar evolution
2023年1月25日 · Diagrams of late stellar evolution typically depict stages such as the Red Giant phase, the Helium-burning phase, the Asymptotic Giant Branch (AGB) phase, and the eventual outcomes like planetary nebulae and supernovae, leading to the formation of white dwarfs, neutron stars, or black holes.
Stellar evolution simulation engine or software
Regarding some of the comments to the question, stellar evolution is actually quite fast, depending what code you use. Certainly, it isn't like hydrodynamics or N-body simulations like those used in galaxy formation/evolution and large-scale structure simulations.
astrophysics - How does metallicity affect stellar evolution?
2020年10月25日 · The main sequence evolution of a solitary star depends most of all on its initial mass. Other factors influencing its evolution are the initial metallicity, rotation and magnetism. Question: how does the initial sun-like metallicity affect the evolution while the star is on the main sequence, (i) in a star of $1M_\odot$ initial mass
Stellar evolution path and Regression line - Physics Forums
2024年1月15日 · Stellar evolution refers to the process by which a star changes over the course of time. This process is driven by the fusion of elements in the star's core, leading to different stages such as the main sequence, red giant, and eventual end states like white dwarf, neutron star, or black hole.
Why are stellar clusters useful for developing stellar evolution …
2022年5月29日 · In a theoretical stellar evolution model, one of the most basic outputs you can produce are a set of isochrones. What you do is evolve stellar models, all with the same chemical composition, but with a range of masses, and stop them all at the same age.
The stellar evolution. Low Mass stars - Physics Forums
2012年6月7日 · FAQ: The stellar evolution. Low Mass stars What is stellar evolution? Stellar evolution is the process by which a star changes over time, from its initial formation to its eventual death. What is a low mass star? A low mass star is a star that has a mass less than about 8 times that of the sun. How do low mass stars evolve?

2024年9月4日 · How does metallicity affect stellar evolution? The main sequence evolution of a solitary star depends most of all on its initial mass. Other factors influencing its evolution are the initial metallicity, rotation and magnetism.
Question regarding two specific books on stellar structure
2024年12月27日 · I have a question regarding two specific books on stellar structure. Stellar structure and evolution 2nd Ed by Kippenhahn... and Stellar interiors 2nd Ed by Hansen... Can someone who is familiar with both of them compare their strengths and weaknesses and recommend one of them for serious...
stellar evolution - Why don't main sequence stars continuously …
2020年7月19日 · The evolution for lower and higher mass stars is different. Lower mass stars achieve a degenerate core prior to reaching the SC limit. Higher mass stars leave the main sequence with a core higher than the SC limit already. If you really are talking about main sequence stars then there seems to be a false premise.
stellar evolution - Are stars getting more metal-rich, less massive …
Therefore the stellar "ecological cycle" of birth and death results in an overall increase in the metal-richness of the interstellar medium and hence the stars that are then produced. To understand exactly the rate at which this occurs requires a …
