Top: characteristic time τeff as a function of νmax. The dots have the same meaning as in Fig. 1. The green curve correspond to a linear scaling in while the red curve is a power law of the form with the slope p = −0.94 obtained by fitting the power law to the theoretical values of τeff (filled red squares). The filled green square corresponds to the value τeff = 173 s found for the solar 3D model (the last model in Table 1). Bottom: τeff as a function of the scaling z2 = (νmax/νref) (ℳa/ℳa,0) where ℳa is supposed to scale according to Eq. (17). The symbols have the same meaning as in Fig. 1. The green line corresponds to a linear scaling in z2, while the red curve to a power law of the form where the slope p = 0.98 is obtained by fitting the theoretical values of τeff (red squares). The horizontal error bars show the uncertainty in z2 associated with a typical uncertainty of 100 K (rms) in Teff. The blue horizontal error bar corresponds to a typical MS and the black one to a typical RG star.
