Query: Constraining Neutrino Cooling using the Hot White Dwarf Luminosity
  Function in the Globular Cluster 47 Tucanae   We present Hubble Space Telescope observations of the upper part (T_eff> 10
000 K) of the white dwarf cooling sequence in the globular cluster 47 Tucanae
and measure a luminosity function of hot white dwarfs. Comparison with previous
determinations from large scale field surveys indicates that the previously
determined plateau at high effective temperatures is likely a selection effect,
as no such feature is seen in this sample. Comparison with theoretical models
suggests that the current estimates of white dwarf neutrino emission (primarily
by the plasmon channel) are accurate, and variations are restricted to no more
than a factor of two globally, at 95% confidence. We use these constraints to
place limits on various proposed exotic emission mechanisms, including a
non-zero neutrino magnetic moment, formation of axions, and emission of
Kaluza-Klein modes into extra dimensions.
