Notes. The various columns report the initial mass of the star, the core mass when the first TDU episode takes place, the core mass and luminosity of the star when becoming a C-star, the percentage duration of the C-star phase, relative to the whole TP life, the final carbon excess with respect to oxygen (defined as 12 + log((n(C)−n(O))/n(H)), where n(i) is the surface number density of the ith species), and the maximum λ (see text for definition) experienced.
