Fig. 5. The position of SMC carbon stars on the HR diagram. Dots represent the data from Westerlund et al. (1991), crosses - from Westerlund et al. (1995). The solid line contours denote, according to our calculations, the regions occupied by the E-AGB stars (left region) and by the TP-AGB stars (right region). The calculations were performed assuming and a tenfold jump of mass loss intensity for . The dashed line contour denotes the E-AGB region according to calculations by Fagotto et al. (1994) for
