What happens when a star uses its hydrogen?
When a star uses the hydrogen in its core it will start burning hydrogen in a shell around the core and become a red giant. After that the star will either collapse into a white dwarf or start fusing helium, depending on its mass.
What does a main star become after it uses up the hydrogen in its core?
See related question.
What will the sun become in the distant future?
As the Sun uses up its supply of hydrogen over billions of years, it will begin to expand into a red giant star. Eventually the star will suffer a catastrophic collapse and throw off mass to form a planetary nebula, and become a small white dwarf star near the center.
What is the name of the portion of a stars life were it uses hydrogen as fuel?
A star that uses hydrogen as fuel is a main sequencestar.
What will be the sun be white dwarf or a main-sequence star?
Right now the sun is a main sequence star. When it uses up the hydrogen in its core it will become a red giant then shed its outer layers to become a white dwarf.
What is the name for the portion of a star's life cycle when it uses hydrogen for fuel?
The portion of a star's life cycle when it uses hydrogen for fuel is called the main sequence stage. During this stage, the star fuses hydrogen to form helium in its core, releasing energy in the process. This is the longest and most stable stage in a star's life.
What is formed once a star's core uses up its supply of helium?
a black hole
What happens during the Main Sequence stage of a star?
It uses up most of the hydrogen it started with.
What happens when a star uses hydrogen?
A neutron or white dwarf star is created in most cases when the star isn't large enough to collapse under its own weight and form a black hole. Our sun will be one of those stars.
Can nuclear fusion continue indefinitely?
Nuclear fusion, like any process of producing power, uses fuel in doing so. In the stars, where fusion is the source of their energy, hydrogen is being used in fusion, producing helium plus energy. In any star the supply of hydrogen will eventually run out and the star will die, but its lifetime will be immensely long, many billions of years. On earth, if fusion can be made to work, it will use isotopes of hydrogen which are abundant, so as a source of energy it would last for many thousands of years.
How can you use hydrogen?
what are some uses hydrogen
What happens to a star when hydrogen burns out?
The star first expands into a red giant (or a supergiant star if the original star was a giant star) and then explodes in a fusion flash (sun-size star), nova (slightly larger), or supernova (for a supergiant).
