* Yellow stars, like our Sun, will become white dwarfs. After the Sun runs out of hydrogen fuel in its core, it will expand into a red giant. This will be followed by a period of instability, where the Sun sheds its outer layers, leaving behind a hot, dense core called a white dwarf.

* But, not all white dwarfs come from yellow stars. Stars of different masses have different evolutionary paths. White dwarfs can also form from:

* Red dwarf stars: These are much smaller and cooler than our Sun, and they have much longer lifespans. They eventually become white dwarfs as well, though the process takes much longer.

* Blue dwarf stars: These are much larger and hotter than our Sun. They evolve into white dwarfs after a shorter lifespan than yellow stars.

So, while white dwarfs are the final stage for yellow stars like our Sun, they are also the final stage for other types of stars. The specific path to becoming a white dwarf depends on the star's initial mass and composition.
