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.
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.
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.
How big is pollux?
Pollux is a bright giant star in the constellation of Gemini. It has a radius about 8.9 times that of the Sun, making it a quite large star. Its size is a result of its advanced evolutionary stage and the processes happening in its core.
What is the core radius?
The core radius refers to the radius of the central region of a structure, such as a star, planet, or fiber. In astrophysics, it often denotes the size of the dense, central part of a star where nuclear fusion occurs. In materials science, it can describe the radius of the core of a fiber optic cable or composite material. The specific definition can vary depending on the context in which it is used.

What happens when a star can't hold it's weight?

And then if the star explodes into a supernova, traces of the higher elements are fused as well.
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
What happens when a medium star's temperature reaches 200000000 degrees Celsius?
helium atoms fuse to form carbon atoms in the core of the star
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.
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 in the core that marks the birth of a star?
Nuclear fusion, converting hydrogen nuclei into helium nuclei.
