Title: Assessment of the tip-AGB mass loss by means of synthetic stellar samples in the (M_bol, J-K) diagramme
Abstract: Using the sophisticated, pulsating and dust-driven Berlin wind models in connection with a grid of individual stellar evolution models (for solar abundances), a large synthetic sample of tip-AGB cool giant stars with very strong mass loss has been computed, including the IR properties. For the first time, we can offer such a synthetic sample for a direct comparison with IR observational data, using the $M_{\rm Bol}$ - (J-K)diagram. The synthetic sample provides a detailed inventory of the individual stellar mass loss, the stellar masses (present and initial) and ages.
