Cooling tracks for white dwarfs

with helium core


The binary stars at the beginning of mass transfer consist from 1.4 Msun neutron star and 1 Msun red giant with small helium core (Mcore < 0.05 Msun). In tables bellow we show cooling tracks for different white dwarfs masses. The metalicity is Z=0.030 where Zcno= 0.0154.
