The term is "protostar", not "prostar". Yes. A protostar is an early stage of a star.
On the contrary, "protostar" is the name of an early stage in the development of a star.
through the process of fusion, it becomes a star: the birth of the star is the start of fusion. therefore, it is after fusion that it is classified as a star.
Star Birth as a Protostar. Stars are born within molecular clouds in the Galaxy. The mass of a protostar determines its place on the H-R diagram, its energy source, its ultimate fate. Then, the final stage when the core is fused to iron.
To see images of a protostar, one would go inside a Bok Globule. This might be hard to do, considering the fact that a protostar is the gas of a giant molecular cloud. But hey, if you can get there, it'd be a sight to see!
The term is "protostar", not "prostar". Yes. A protostar is an early stage of a star.
The basic idea is that the protostar contracts, under the influence of gravity, until it gets dense and hot enough to undergo nuclear fusion. You can find more details at the Wikipedia article "Protostar".
The formation of a protostar from a nebula. As the protostar forms, it accretes more mass from the cloud and spins. As it gains more mass, it eventually becomes massive enough to ignite the core and become a star. The protostar is the first step in the evolution of any star.
A protostar does not burn fuel as it is still taking part in nuclear fusion. It is, however, preparing to become a main sequence star, and will then burn mostly hydrogen at that stage.

the color of the protostar is red
A Protostar.
As gravity pulls more material toward the center of the protostar, the pressure inside the protostar builds.
A protostar is a star that is in the early stages of formation that has not yet become a main sequence star. A white dwarf is a remnant left behind after a low to medium mass star dies.
A protostar will live as long as 100,000 years. After material stops falling on the protostar it will enter then T Tauri star phase.
A protostar is more like a stage previous to a star - before it ignites.
