∙ 9y agoA protostar is a young star in the early stages of formation, where nuclear fusion has not yet begun. A white dwarf is a small, dense star that is the remnant core of a low to medium mass star after it has exhausted its nuclear fuel.
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 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)
The sun's life cycle includes the stages of formation, main-sequence, red giant, and white dwarf. It is currently in the main-sequence stage, where it fuses hydrogen into helium in its core. Eventually, it will expand into a red giant before shedding its outer layers and becoming a white dwarf.
A star like the Sun begins as a cloud of gas and dust that collapses under gravity to form a protostar. It spends most of its life on the main sequence, fusing hydrogen into helium in its core. Eventually, it will expand into a red giant, shedding its outer layers into space. Finally, it will collapse into a white dwarf, slowly cooling over billions of years.
A black dwarf is a theoretical end-stage of a white dwarf star in the far future, after it has cooled down and no longer emits light. White dwarfs are hot, dense remnants of low to medium mass stars at the end of their evolution.

their colour is one thing but a black dwarf originates from a white dwarf

white dwarf is an age that a star reaches but the big bang is an explosion of nuclear energy that makes a star

A white dwarf is a white hot solid ball of nickel-iron alloy, a black hole is an infinitesimal singularity of infinite density surrounded by total emptiness.
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.

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.
