Protostar

(contracted mass of gas that will become a star)

A Protostar is an early stage in the development of a star, formed from a contracting giant Molecular Cloud and eventually (on the order of 10 million years) becoming a T-Tauri Star or other type of Pre-Main-Sequence Star. The protostar is heated by the release of gravitational energy as the gas contracts rather than by Fusion. It will eventually ignite fusion and become a Main Sequence Star.
