Comparison of various parameters as a function of mass for ASAS-09 (inner pair) and ASAS-21 with several sets of isochrones. Left column is for the age of 1 Gyr and nearly-solar metallicity, middle column is for 5 Gyr and Z = 0.02, right column is for 1 Gyr and metal-enriched composition: 0.03 for PADOVA, and 0.04 for Y2 and GENEVA (available for M ≥ 0.8 M). For the comparison we also show an isochrone of Y = 0.282 for BCAH98.
