Density and temperature structures for constant opacity runs in radial and vertical slices after ten orbits: data are shown for runs with and the nominal run with and N_c= 100 for comparison. A deeper potential raises the whole envelope temperature as long as no convective region is formed. Optically thick regions are hotter for higher opacity (see inset), while the optically thin regions approach isothermal structure and their temperature trend reverses according to the position of the τ = 1 surface (indicated with triangles). The density structure follows simple expectations: a hotter envelope has lower density in optically thick regions.
