Query: Faint Cataclysmic Variables in Quiescence: Globular Cluster and Field
  Surveys   Current evolutionary models imply that most Cataclysmic Variables (CVs) have
P_orb<2 hours and are Dwarf Nova (DN) systems that are quiescent most of the
time. Observations of nearby quiescent DN find that the UV spectrum is
dominated by the hot white dwarf (WD), indicating that it provides a
significant fraction of the optical light in addition to the quiescent disk and
main sequence companion. Hence, identifying a faint, quiescent CV in either the
field or a globular cluster (GC) from broadband colors depends on our ability
to predict the WD contribution in quiescence. We are undertaking a theoretical
study of the compressional heating of WDs, extending down to very low time
averaged accretion rates, <Mdot>~10^{-11}M_sun/yr, which allows us to
self-consistently find the T_eff} of the WD. We demonstrate here that most of
the compressional heating occurs in the freshly accreted envelope and that the
WD core temperature reaches a fixed value on a timescale less than typical
evolutionary times. Since nuclear burning is unstable at these <Mdot>'s, we
have incorporated the recurrent heating and cooling of the WD core throughout
the classical novae limit cycle in order to find the T_eff-<Mdot> relations.
Comparing to observations of field DN confirms the <Mdot>-P_orb relation of
disrupted magnetic braking. We also predict broad-band colors of a quiescent CV
as a function of <Mdot> and companion mass and show that this leads to the
identification of what may be many CVs in deep HST images of GCs.
