Visual fit of observed classical parameters of the system with theoretical tracks and isochrones from the YaPSI database (Spada et al. 2017). Left: comparison in the mass radius plane with isochrones of different ages for the primary (top panel) and the two components of the inner binary (bottom). Right: comparison in the radius-luminosity plane; a 4.5-Gyr isochrone and evolutionary tracks of appropriate mass and metallicity are shown.
