Question

A protostar is _____. the stage before a star becomes a main sequence star a small star that will continue as a main sequence star for hundreds of billions of years a star with a core of neutrons a region of space from which light cannot escape the stage after a star completes its main sequence existence

Answer 1

the stage before a star becomes a main sequence star

Answer 2

Answer:

5.the stage before a star becomes a main sequence star

Explanation:

A protostar is the situation that exists before the formation of a star, in the protostar there is a molecular cloud of gas and particles.

These gases and particles contract more and more due to gravity until the gases begin to heat up and become so dense that a hydrogen fusion process begins and this is where a main sequence star is formed.

The main sequence is the region of the Hertzsprung-Russell diagram in which most of the starst are found, which are the stars that fuse hydrogen in its nucleus.

In Summary, a protostar is the stage before a star becomes a main sequence star.
