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 to the core of a star after a planetary nebula occurs?
It becomes a white dwarf.
What happens when the outer core of a star explodes after the core collapses?
Its blown into interstellar space - to enrich and mix with the gasses already out there.
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 happens when a star can't hold it's weight?
The core collapses

What happens in the star core?
The core of a star is located inside the star in a region where the temperature and pressures are sufficient to ignite nuclear fusion, converting atoms of hydrogen into helium, and releasing a tremendous amount of heat.
When a stars core collapses does a giant explosion happen?
Yes, if the star is massive enough when the core collapses a supernova explosion happens.
When the core of a star reaches a temperatureof about 100 million degrees K something new happens in the core What is this new event?
As an average star is dying and the core is contracting when the temperature reaches 100 million Kelvin Helium atoms fuse into
Why the temperature of the stars vary from one another?
The temperature in the core of a star depends, to a great extent, on:* The star's mass. The general tendency is that high-mass stars are hotter. * Where the star is in its life cycle. The star's core temperature will vary over time. On the other hand, the star's surface temperature also depends on its size. Thus, it is possible that PRECISELY because a star is hotter in the core, it gets bigger, and the surface temperature DECREASES (though its total energy output increases).
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 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.
