In fact, the sun is not massive. It is an average, yellow star. When the sun goes into its next stage, it becomes a red giant. This could consume the whole solar system. Then, when it burns out, the gases escape into space, and it becomes a little tiny star called a white dwarf. Eventually it will burn out, and that's how the sun's lifecycle works.

what is the third stage of the star cycle
A star with a mass of 2solar masses, 2times the mass of the sun, would have a main-sequence stage of half the life of a star with the mass of our sun. More massive stars die faster, less massive stars live longer and therefore have longer main-sequence stages.
white dwarf
Technically, no, it's not the final stage. The final stage would be a black dwarf... a completely burned-out star.
For a star like ours, the black dwarf stage For an immensely massive star, a back hole.

redgiant
White Dwarf then Black Dwarf=Dead Star

It varies, depending on the stage of the star's development.
yes, it is the stage where a star dies and turns into a blackhole

white dwarf
It doesn't differ from a star, it is a star and it is the second stage in a stars life after the nebula stage.
