White Dwarf Mergers: Before And After

Even though we now know of many white dwarf binaries in our Galaxy, there is
still much uncertainty about what happens when they merge due to gravitational
wave emission. I will discuss theoretical work about the tidal interaction
between the white dwarfs, how the tidal dissipation imprints itself on the
inspiral, and the ramifications the tides have for the merger. Next I will
explore the possible observational signatures expected when the total mass of
the binary exceeds the Chandrasekhar limit.
