Dissipation Efficiency in Turbulent Convective Zones in Low Mass Stars

Abstract

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)
