What happens to a sun like like star after it has used up all its core fuel?

Once a sun-like star has used up almost all of the hydrogen in it's core it will start to burn helium as well. This starts it's Red Giant phase which drastically increases the size of the star to hundreds of it's original size. Once the star has used up all available fuel it will contract down to the size of the Earth. While shedding it's outer layers into a Nebula. The Star is now a White Dwarf and will slowly fade into a Black Dwarf after trillions of years.

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 happen to a sun-like star after it has used up all the fuel in its core?
Towards the end of its life, a star with a size similar to ours will expand to a red giant star as the core contracts and heats up and the hydrogen fuel supply is consumed. It will eventually lose the outer layers and all that will be left is a core, a white dwarf reminant that will slowly cool over millions of years.
What happens when a neutron star runs out of fuel?
Neutron stars do not have fuel. A neutron star is a remnant of a star that has already died.
If the core temp of a star decreases what happens to the radius?
It increases
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 is in a star's core?
A star's core consists mostly of hydrogen. As the star ages, the amount of helium, carbon and other elements in the core increases as they are the result "ash" resulting from the consumption of the hydrogen fuel.

What happens to Hydrogen atoms in a star's core?
its clears air

It increases
How is the red-giant formed?
A red giant forms when a star runs out of hydrogen fuel at its core and starts fusing hydrogen in a shell around the core the core. This causes the star to expand and cool.
What happens when a star can't hold it's weight?
The core collapses
When a main sequence star runs out of hydrogen to fuel the core of which type of star begins to form?
red giant
When a main sequence star has the fuel in its core it becomes?
The next step in its life is to become a "red giant" star.
What happens to the core of a star after a planetary nebula occurs?
It becomes a white dwarf.
