Consider the following possible stages in the evolution of a star like our sun: black dwarf, giant, main-sequence, planetary nebula, supernova, white dwarf. Rank the stages in the order they occur. Leave out any stages that will not occur in the evolution of a star of similar mass to the sun

Main sequence

Giant

Planetary nebula

White dwarf

Black dwarf

Explanation:

Main Sequence:

Stars are called main sequence stars when their core temperature reaches up to 10 million kelvin and their start the nuclear fusion reactions of hydrogen into helium in the core of the star. For example sun is known as to be in the stage of main sequence as the nuclear fusion reactions are happening in its core.

Giant:

Next step is the Giant phase. When the stars run out of their fuel that is hydrogen for the nuclear fusion reactions then they convert into Giant stars. Giant stars have the larger radius and luminosity then the main sequence stars.

Planetary nebula:

Planetary nebula consists of glowing gases and plasma, it ejects from the red giant stars that run out of their fuel.

White dwarf:

When the stars run out of their fuel then they shed the outer layer planetary nebula, the remaining core part that left behind is called as white dwarf. It's the most dense part as the most of the mass is concentrated in this part.

Black dwarf:

When the white dwarf cool down completely that it no longer emitt heat and light then it is called as black dwarf.

These were the possible stages that includes in the evolution of stars
