Mass loss measured using asteroseismic observables for M4, NGC 6791 (Miglio et al. 2012), NGC 6819 (Miglio et al. 2012; Handberg et al. 2017, H17), M 67 (Stello et al. 2016), and the α-enhanced stars in the Kepler field (Kα, Miglio et al. 2021) as function of age (left) and metallicity (right). Two sets of models for different (Reimers 1975) mass loss parameter, ηR = 0.25, 0.50, are included for comparison purposes.
