We use a heat conduction prescription based on the Kramers opacity law which allows the depth of the convection zone to dynamically adapt to changes in …

WebKramers' law is a formula, derived in 1923 by the Dutch physicist Henrik Kramers (1894–1952), for the opacity of material inside a star. It states that, at high temperature, … WebHere we use a= 1 and b= 7=2, corresponding to Kramers opacity law for free-free transitions (Weiss et al. 2004). The radiative diffusivity ˜= K=ˆc P can vary by several orders of magnitude as a function of depth in the Kramers opacity case. In order to keep the simulations numerically stable, we apply additional turbulent SGS diffusivities in the
