How does a white dwarf form
WebWhen a star like our Sun dies, it doesn’t explode into a supernova or collapse into a black hole. Instead, it gently sheds its outer layers, which form a beautiful cloud called a “planetary nebula”, while the dying star’s core becomes a white dwarf. WebWhite dwarfs have exhausted all their nuclear fuel and so have no residual nuclear energy sources. Their compact structure also prevents further gravitational contraction. The …
