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.

∙ 15y agoThe gravity of the cloud causes the cloud to collapse to a center (the proto star). As the hydrogen condenses into the star, the gravitational energy released cause the center to heat up and this heat together with the weight of the overlying hydrogen provides an environment in the core of the proto star in which the nuclear fusion of the hydrogen into helium can occur. This fusion is one in which mass is converted into energy (e-mC2) and the proto star turns into a star. A star is a blance between gravity trying to pull the hudrogen into a tight ball and the nuclear explosion in the core trying to force the hydrogen apart.

∙ 12y agoGravity causes the hydrogen molecules to gather together, this causes a strong gravitation pull towards the centre mass, more hydrogen atoms are attracted. Eventually a protostar is formed. As the mass of the protostar increases, the temperature and pressure at the centre increases. When the temperature reaches 10 million degrees Kelvin fusion starts and a star is born.

∙ 13y agoA hydrogen cloud is already hydrogen gas. So it can not become hydrogen gas.

∙ 6y agoA star will fuse hydrogen - mainly hydrogen-1 - converting it into helium-4, and releasing a large amount of energy in the process.

What happens during the third stage of a stars life cycle as the star uses up all of its hydrogen?
The core of a star contracts under the force of its own gravity. This contraction increases the temperature in the core.
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.
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.
Reaction dead star?
A dead star is one that no longer experiences nuclear fusion. This happens when a star runs out of hydrogen it can use to convert to helium.
What happens in the core that marks the birth of a star?
Nuclear fusion, converting hydrogen nuclei into helium nuclei.
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 happens when a star burns up 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 for the portion of a star's life cycle when it uses hydrogen for fuel?
When a star is in the Hydrogen burning phase it said to be a Main Sequence star.
What happens during the third stage of a stars life cycle as the star uses up all of its hydrogen?
The core of a star contracts under the force of its own gravity. This contraction increases the temperature in the core.
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.
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.

Do bigger stars use hydrogen more rapidly?
Yes.The larger the star, the quicker it uses up it's hydrogen
