Maximum luminosity (top-left panel) and temperature at the base of the envelope (top, right) experienced by our AGB models of metallicity Z = 0.03 (red squares) and Z = 0.04 (blue diamonds) as a function of the initial mass. The bottom panels show the duration of the TP-AGB phase (left) and the final C/O (right). For comparison, we also show solar metallicity models by Ventura et al. (2018) (black points), Z = 0.03 models by Karakas (2014) (green triangles), and Z = 0.04 models by Weiss & Ferguson (2009) (magenta asterisks).
