A stars core is made up of mostly hydrogen. If you want the real numbers it is: 73% hydrogen, 25% helium, and the last 2% is all the other elements of the period table.
Nucleosynthesis in the core of stars.
These are stars that have exhausted their core's supply of hydrogen by switching to a thermonuclear fusion made of hydrogen in a shell that surrounds the core.
A stars core temperature will be several million kelvins
Nuclear Fusion occurs in the core of stars.
Nuclear Fusion at the Stars' Core.
Most stars, particularly in their core, are made mostly of hydrogen and helium. These elements are the most abundant in the universe and are the building blocks of stars through nuclear fusion reactions.

A white main sequence star has the hottest core.
They are called Core Burning Stars the smallest one is OGLE-TR-122b.
What happens to a stars nuclear energy generation change if the core decreases in temperature?
No. They don't contain rock particles that shine.
