A star forms from a cloud of gas and dust that collapses under the force of gravity. As the cloud becomes more compressed it heats up, eventually becoming hot enough to fuse hydrogen.
Stars are not powered by combustion; they are powered by nuclear fusion, which is a fundamentally different and far more energetic process.

No. That's precisely the main difference between planets and stars - that stars can have nuclear fusion, planets not.
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'
