Description:
We present a set of evolutionary tracks for white dwarfs with helium
cores in the mass range from 0.179 to 0.414M☉. The tracks are
based on a 1M☉ model sequence extending from the pre-main
sequence stage up to the tip of the red-giant branch. Applying large
mass loss rates at appropriate positions forced the models to move off
the giant branch.The further evolution was then followed across the
Hertzsprung-Russell diagram and down the cooling branch.
