[owxanyzo] a song of fire then ice

red giant, then white dwarf: winter is coming, but we have to survive fire first.

if your local star weighs more than about 10^58 amu, the fire will be crazy violent: supernova.  fortunately, our sun is less, about 10^57 amu.

(the lowest mass red dwarfs are about 10^56 amu.)
