Gravity causes them to contract, and they become fainter because of their smaller sizes.. After contracting for millions of years, stars eventually become hot enough to fuse hydrogen, which halts their contraction. They now maintain a stable size and luminosity until they run out of hydrogen fuel. This is the . PROTOSTAR. Region of . gas. and . dust . create a nebula.
