The absolute value of the maximum expected rates of period change, (s/s), and the sign, for nonradial ℓ = 1g and p modes (and p−g mixed modes in the case of pre-ELMVs), and for radial (ℓ = 0) modes corresponding to low-mass WD and pre-WD models and also objects evolving just before the CNO flashes.
