    The (hot) core of a low mass star becomes a white dwarf and surface temperatures range from 10 000 K to 20 000 K.

    I thought this was going to be the lead-up to some awful racist joke. So I clicked the thread title.

    I'm not 100% sure but I think it's because as the star contracts the P.E of the particle's decreases and their K.E increases, since K.E is proportional to T, the temp rises. The reason the temperature is sooo high is because there is a huge collapse as a star becomes a white dwarf hence there is a huge decrease in P.E of the particles hence a huge increase in K.E and also temperature.
