Answer:
1.) Nebular cloud of gas and dust.
2.) Cloud collapses under the force of its own gravitational attraction; usually triggered by a supernova.
3.)Condensed material begins to combine and form a core center, as it warms, a protostar is formed.
4.)Other gas and matter of the nebular cloud begin to rotate around the protostar, forming a flattened disk.
5.) Stellar core heats as it grows; nuclear fusion begins and a star is born.
6.) Nuclear energy runs out; death: possible supernova.
