Query: Seven-Period Asteroseismic Fit of the Kepler DBV   We present a new, better-constrained asteroseismic analysis of the
helium-atmosphere (DB) white dwarf discovered in the field of view of the
original Kepler mission. Observations obtained over the course of two years
yield at least seven independent modes, two more than were found in the
discovery paper for the object. With several triplets and doublets, we are able
to fix the $\ell$ and $\rm{m}$ identification of several modes before
performing the fitting, greatly reducing the number of assumptions we must make
about mode identification. We find a very thin helium layer for this relatively
hot DB, which adds evidence to the hypothesis that helium diffuses outward
during DB cooling. At least a few of the modes appear to be stable on
evolutionary timescales and could allow us to obtain a measurement of the rate
of cooling with monitoring of the star over the course of the next few years
with ground-based follow-up.
