A first pulsating white dwarf has been discovered recently in the Kepler field of view [1]. This star, catalogued as GALEX J192904.6+444708 or KIC 8626021, is a He-atmosphere white dwarf of the V777 Her (DBV) type. It appears to be the hottest of its class and, as such, has the potential to be a key object in our understanding of the DB gap problem. We present here a seismological analysis of this star and a look at his previous history.
