Evolutionary track of the 0.84  M_⊙ model in the asteroseismic H.-R. diagram (blue). The black diamond indicates the position of the selected model. The dashed red and green lines correspond to the errors bars on the observed large separation and period spacing, respectively, from Deheuvels et al. (2012). These error bars have been magnified 40 times for the large separation and 400 times for the period spacing to be visible.
