A protostar is a star the is developing as is on the way to starting nuclear fusion. A brown dwarf is a failed star, one that failed to gather enough mass to start fusion.

What is a possible outcome for a protostar that does no have enough material?
A brown dwarf.A brown dwarf.A brown dwarf.A brown dwarf.
What is the difference between the protostar and the white dwarf?
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.
Which type of star is NOT undergoing nuclear fusion?
A protostar; also a brown dwarf.
Does a star change during its life cylcle?
Yes. The possible cycle is: protostar/brown dwarf main sequence star red giant supernova/super giant white dwarf/black hole black dwarf
What is a brown dwarf?
A brown dwarf is a celestial object that has a size that is between a star and a giant planet.
What is the differences of a protostar and a white dwarf?
A protostar is a star that is still forming and has not yet started a sustained fusion reaction. All the heat is the result of gasses being compressed. A white dwarf is the remnant of a dead star that has exhausted its fuel and is much smaller and denser than a protostar.

What are the stages of the sun's life cycle?
protostar, main sequence, giant, nebula, white dwarf & black dwarf.
What is the life cycle of a yellow star?
Nebula protostar mid sized star red giant nova white dwarf black dwarf:)
What is the difference between red and brown dwarf stars?
Red dwarf stars are massive enough to undergo nuclear fusion, so they would burn a long time before they run out of fuel. Brown dwarves are not massive enough for nuclear fusion, so almost all of its light come from the time when the brown dwarf was formed. Over a long period of time, a brown dwarf would cool down into a gas giant similar to Jupiter.
How is a protostar created?
Sometimes. If the total mass is high enough, and if the cloud of dust and gas collapse to reach a high enough density and pressure, nuclear fusion can begin in the core and it will become a star. If the total mass is not high enough, it may collapse into a "brown dwarf".
What is difference between hobbit AND dwarf?
The hobbit is much shorter than a dwarf. Hobbits do not have beards.
