nuclear fusion
The stars produce their heat from nuclear fusion reactions. Work on earth to produce controllable nuclear fusion is concentrating on one particular reaction, between deuterium and tritium, because it is the easiest to get going (though hard enough!). Stars operate with other reactions but all of the nuclear fusion type. You can read more in Wikipedia 'Nuclear fusion'

Nuclear Fusion
Combining two atomic nuclei is called nuclear fusion.
Fusion is a nuclear reaction.
The idea of nuclear fusion occurring at room temperature is called cold fusion.
Nuclear fusion produces nuclear energy
That would be nuclear fusion, like what happens in stars, when two hydrogen nuclei combine to form a helium nucleus.
The fusion of Hydrogen into Helium causes heat and radiation to occur.
