The paper calculates how accretion affects the evolution of carbon-oxygen white dwarfs up to thermonuclear runaway. The influence of internal temperature (including the possibility of solidification) as well as that of other initial conditions (accretion rate, total mass) is taken into account. The influence of the adopted pycnonuclear reaction rate and of the lattice impurities on the ignition conditions is examined. The consequences of having a completely ordered C-O crystal instead of a disordered one are also analyzed.
