When a star has used up all the hydrogen in its core, it has reached the end of the main sequence. Subsequent developments depend on the mass and composition of the star. Sun-type stars may expand and continue to fuse ever heavier elements in and about their core, until fusion no longer yields sufficient energy to prevent collapse.
What else can I help you with?
How is the lifetime of a star comparable to stellar evolution?
Stellar evolution is the term for the changes a star undergoes during its lifetime.
What are Endpoints of stellar evolution?
The endpoints of stellar evolution are: White Dwarf Neutron Star Black Hole The endpoint is dependent upon birth mass of the star.
What is a good science fair title dealing with star life cycle?
Life Cycle of a Star
What current stage of stellar evolution is Arctics?
I know of no star by that name.
How can star clusters confirm astronomers' theories of stellar evolution?
Star clusters are collections of same-age stars that remain intact for billions of years. When plotted on a H-R diagram, a cutoff point of stars leaving the main sequence and massive stars further evolved are shown, confirming the theory of stellar evolution.
Can a planet become a star through a process of stellar evolution?
Yes, a planet cannot become a star through stellar evolution. Stars are formed from collapsing clouds of gas and dust, while planets are formed from the leftover material in a star's protoplanetary disk.
How does gravity effect stellar evolution?
Gravity effects stellar evolution by pulling down force on the stars while they are forming. Mass will determine how long the star stays alive and burning.
What describes the life of a star?
Stellar evolution is the collection of hypotheses that describes how stars develop as they age.
What is a stellar spectra?
Stellar spectra are graphs or visual representations of the intensity of light emitted by a star at different wavelengths. They provide information about the star's temperature, chemical composition, and motion towards or away from Earth. Studying stellar spectra is crucial for understanding the properties and evolution of stars.
What is the main sequence stage?
The main sequence stage is a point in the stellar evolution of stars in the universe at which every star converts hydrogen into helium in its cores and releases huge amounts of energy.
What determines the evolution of a star?
The mass of a star affects the lifespan of the star. The less the mass, the longer life span of the star. More massive stars burn up their fuel more quickly than the smaller stars. As the massive stars begin to burn the fuel and become smaller, the life span increases.
What major forces and or pressures drive stellar evolution?
The fact that each star starts out with all the hydrogen that its ever going to have.
