What is the temperature of a star when it dies?

Answer 1

The temperature of the star when it dies is 350 degrees celsius

Answer 2

The temperature of a star when it dies depends on its mass. Low to medium mass stars, like our Sun, will cool and expand into a red giant before shedding their outer layers to form a planetary nebula. The remaining core will eventually cool into a white dwarf, with temperatures around 10,000 K. Higher mass stars can end their lives as supernovae, neutron stars, or black holes, with temperatures reaching millions of degrees.
