Notes. Also listed are the delays, Δtcool, in Gyr (and the relative delays, , in parenthesis) of white dwarf cooling times at the stellar luminosity log(L/L) = − 5 caused by exsolution alone, crystallization alone, and both processes combined, all with respect to the cooling sequence that disregards both processes.
