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.
What else can I help you with?
When the core of a star shrinks after hydrogen fusion stops the core heats up but what happens to the star?
The rest of the star expands.
Where does hydrogen fusion occur when there is no hydrogen left in the core of a star?
If there is no hydrogen left at the core of star then hydrogen fusion cannot occur. What happens in the core of a star before that happens is that helium begins to fuse, and then the other elements going up the periodic table until carbon. And then if the star explodes into a supernova, traces of the higher elements are fused as well.
What happens in the core that marks the birth of a star?
Nuclear fusion, converting hydrogen nuclei into helium nuclei.
What happens during the third stage of a stars life cycle as the star uses up all of its hydrogen?
During the third stage, a star expands and becomes a red giant as it runs out of hydrogen fuel in its core. The core contracts and heats up, causing the outer layers to expand. Eventually, the star will shed its outer layers to form a planetary nebula, leaving behind a dense core called a white dwarf.
How is a star able to begin helium fusion after it ran out of hydrogen?
The basic idea is that once a star runs out of hydrogen fuel, it starts contracting until it gets hot enough to fuse helium into heavier elements. This happens at temperatures that are quite a bit higher than the temperatures required to fuse hydrogen into helium.
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 happens during the Main Sequence stage of a star?
It uses up most of the hydrogen it started with.
What happens when a star burns all of its hydrogen?
When a star burns up all of its hydrogen,it becomes red in color.As hydrogen is the fuel for star and it will burst after it.
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 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 happens to Hydrogen atoms in a star's core?
its clears air
What will a star become as it uses up its hydrogen supply?
a super giant.
When the core of a star shrinks after hydrogen fusion stops the core heats up but what happens to the star?
The rest of the star expands.
Where does hydrogen fusion occur when there is no hydrogen left in the core of a star?
If there is no hydrogen left at the core of star then hydrogen fusion cannot occur. What happens in the core of a star before that happens is that helium begins to fuse, and then the other elements going up the periodic table until carbon. And then if the star explodes into a supernova, traces of the higher elements are fused as well.
What does a main star become after it uses up the hydrogen in its core?
See related question.
How do black holes happen?
It happens when a star 8 times bigger than the sun(if the star is bigger it uses up more fuel/hydrogen)starts to run out of fuel and turns helium into heavier elements and when it finally reaches iron it collapses and turn into a neutron star, then a black hole.
What happens when a candle lit?
The hydrogen and the carbon dioxide mix. Candle uses oxygen and wax as fuel
