Schematic overviews showing the dynamic behavior of solar-mass models for C-type AGB stars as a functionof input parameters. From top to bottom panels: wind maps for models with solar metallicity ([Fe∕H] = 0), LMC metallicity ([Fe∕H] = −0.5), and SMC metallicity ([Fe∕H] = −1.0). The red boxes represent models with a stellar wind, the blue boxes represent models with no wind, and the green boxes represent models with episodic mass loss. For each combination of luminosity and effective temperature the carbon excess and piston velocity are varied as indicated by the inset box.
