Time dependence of the various energy sources and sinks for our 0.53512 M⊙ and 0.82623 M⊙ white dwarf sequences resulting from progenitors with Z = 0.0001. It depicts the surface luminosity L⋆ (solid line), the luminosities arising from the proton-proton chain Lpp (dashed line), and from the CNO bi-cycle LCNO (dotted line), the energy loss by neutrino emission Lν (dot dashed line), and the gravothermal (compression plus thermal) energy release Lg (long dotted line). The domain of the main energy source is also indicated. Time is measured in years since the moment when the star reaches the maximum effective temperature. The progenitors masses are 0.85 and 2.5 M⊙.
