Question

What happens when hydrogen is finished in the core of the sun​

Answer 1

When our Sun runs out of hydrogen fuel in the core, it will contract and heat up to a sufficient degree that helium fusion can begin. ... It will end composed of carbon and oxygen, with the lighter (outer) hydrogen and helium layers blown off. This occurs for all stars between about 40% and 800% the Sun's mass.
