Abstract

I review the seismological structural determinations of ZZ Ceti stars done to date and supplement these with additional preliminary determinations of my own.I compare the constraints on the hydrogen layer mass to see what trends emerge and also determine if the observed hydrogen layer masses are consistent with proposed theories.I then look ahead to the prospects of further DAV white dwarf seismology.
