Question

The medium-sized stars end their life as which of the following?
black dwarfs
neutron stars
black holes
white dwarfs

Answer 1

Medium-sized stars, like our Sun, typically end their lives as **white dwarfs**. After exhausting their nuclear fuel, they shed their outer layers and leave behind a hot core, which becomes a white dwarf. Over a very long period, white dwarfs can cool down and eventually become black dwarfs, but this process takes longer than the current age of the universe, so no black dwarfs are thought to exist yet.
