Query: White Dwarfs in NGC 6791: Avoiding the Helium Flash   We propose that the anomalously bright white dwarf luminosity function
observed in NGC 6791 (Bedin et al 2005) is the consequence of the formation of
0.5 Msun white dwarfs with Helium cores instead of Carbon cores. This may
happen if mass loss during the ascent of the Red Giant Branch is strong enough
to prevent a star from reaching the Helium flash. Such a model can explain the
slower white dwarf cooling (relative to standard models) and fits naturally
with scenarios advanced to explain Extreme Horizontal Branch stars, a
population of which are also found in this cluster.
