What Is A Protostar?
|
The protostar is one of the first stages of a star. The protostar is a mass of dust and gases; the protostar is not very stable, due to many reactions. For the protostar to achieve life as a star it has to maintain equilibrium. Equilibrium in a stars case is balance between gravity pilling atoms towards the center of the protostar and gas pressure pushing heat and light from the center. It is hard to keep equilibrium, when a star can no longer maintain it then it dies.
