This star is not realistic in the surface layers, where the radiative flux limited temperature gradient becomes lower than the convective temperature gradient. the opacity in these layers is dominated by the h-ion, which has a complex opacity law well approximated for solar abundances by: (3) k(p, t) = 2 x 10-18t6p0.8 cm²/g, with t in k and p in g/cmfind the temperature at which the atmosphere becomes sufficiently transparent to radiation for convection to stop. you'll have to approximate the star's luminosity as being equal to 4tr205bt4, where t is the near-surface layer where convection stops. express your answer to the nearest 500 k, e. g. by choosing a single layer in the model output. show working, including the value of d log(t)/dr that applies when convection stops.
