We extend the analysis of Penev et al. (2007) to calculate effective viscosities for the surface convective zones of three main sequence stars of 0.775M ⊙ , 0.85M ⊙ and the present day Sun. In addition we also pay careful attention to all normal-ization factors and assumptions in order to derive actual numerical prescriptions for the effective viscosity as… (More)
