Evolution of stellar parameters and wind properties of our standard model of a 0.595 M_⊙ AGB remnant. Left column: Run of stellar bolometric, L_star/L_⊙ (top), and wind luminosity, (bottom), versus stellar effective temperature. Post-AGB ages t (in units of 1000 yr) are indicated along the tracks by diamonds. Right column: Corresponding mass-loss rate (top) and (terminal) wind velocity versus post-AGB age t (bottom). We followed the recommendations of Pauldrach et al. (1988) for the central-star wind (T_eff ≥ 25 000 K or t ≃ 2000 yr), while we assumed a (Reimers 1975) wind during the transition to the nebula domain (cf. also Perinotto et al. 2004).
