Energy output in white dwarfs.

Forums General Discussion Inner core temperatures of white dwarfs Energy output in white dwarfs.

Dr Paul Leyland

The temperature may be quite low but the density is so high that hydrogen fusion still occurs in white dwarfs. I have seen an estimate that about 5% of the luminosity of a 10,000K WD is due to this process.  I will see if I can dig out the reference if anyone is interested.
