Left panel: evolutionary tracks in the HRD for the nonrotating models computed with the standard mass-loss rates, superposed the positions of progenitors of core-collapse supernovae. Empty stars indicate RSGs (see Table 2), filled pentagons those with a yellow supergiant as progenitors (see Table 6). A continuous segment links the positions of the same SN progenitors obtained by various authors. Progenitors of supernovae predicted by the nonrotating models computed with the various RSG mass-loss rates are found in the shaded area. Progenitors obtained with standard RSG mass-loss rates occupy the upper part as well as the right part of the shaded region, while the progenitors obtained from enhanced RSG mass-loss rate models are in the lower-left region of the shaded area. Lines of constant radius are indicated, the line intermediate between the 100 and 1000 R_⊙ corresponds to a radius of 500 R_⊙. Right panel: same as left panel with evolutionary tracks in the HRD for the rotating models computed with the standard mass-loss rates. Progenitors of supernovae predicted by the rotating models computed with the various RSG mass-loss rates are found in the shaded area.
