There are many types of variable stars. Today we’re gonna talk
about cataclysmic variable stars, which are the result of a white
dwarf stealing material from a companion star. And this whole
process makes supervillain Pamela happy. Gravity is the weakest
force, but on the scales of stars, it is capable of great
violence. In this episode, we look at the wild physics of
cataclysmic variables: binary star systems where one star is a
predatory compact stellar remnant, while the other is a
victimized normal star.
