Abstract

C-stars separate well from O-rich giants in near-infrared colours, drawing a striking red tail in recent colour-magnitude diagrams for Local Group galaxies. Most present-day stellar models are unable to account for this feature. However, it is naturally reproduced when AGB models are computed with consistent variable molecular opacities.
