Abstract:
We present evolutionary calculations and colors for massive
white dwarfs with oxygen-neon cores for masses between 1.06
and 1.28M☉. The evolutionary stages computed cover the
luminosity range from log(L/L☉)∼0.5 down to -5.2.
Our cooling sequences are based on evolutionary calculations that
take into account the chemical composition expected from massive
white dwarf progenitors that burned carbon in partially degenerate
conditions. The use of detailed non-gray model atmospheres provides
us with accurate outer boundary conditions for our evolving models
at low effective temperatures.
