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.
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.
protostar, main sequence, giant, nebula, white dwarf & black dwarf.
Yes. The possible cycle is: protostar/brown dwarf main sequence star red giant supernova/super giant white dwarf/black hole black dwarf
A star with a low mass will go through these stages: 1. Protostar nebula 2. Main sequence (as a red dwarf) 3. Red giant 4. Planetary nebula 5. White dwarf (6. Black dwarf is theorized to occur after white dwarf)
A protostar; also a brown dwarf.

Nebula protostar mid sized star red giant nova white dwarf black dwarf:)
white dwarf is an age that a star reaches but the big bang is an explosion of nuclear energy that makes a star

The mass of the progenitor star has to be massive to form a black hole and thus it will have a shorter time on the main sequence compared to a medium sized star.
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.
A protostar; also a brown dwarf.
A star, the size of our sun, does not explode into a supernova. Instead, toward the end of its life, it grows over 1000 times its size into what is called a Red Giant. After that it implodes and looses mass at a quick rate reaching the white dwarf stage. After that it is a black dwarf and looses all its energy and mass.

Stars have several cycles in their lifespan. The seven cycles of a star like our sun are Stellar Nebula, Protostar, Main sequence star, Red Giant, Planetary Nebula, White Dwarf, and Black Dwarf.
