The effects of numerical resolution on hydrodynamical surface convection simulations and spectral line formation

Asplund, Martin; Ludwig, H.-G; Nordlund, A; Stein, Robert F


The computationally demanding nature of radiative-hydrodynamical simulations of stellar surface convection warrants an investigation of the sensitivity of the convective structure and spectral synthesis to the numerical resolution and dimension of the simulations, which is presented here. <p> With too coarse a resolution the predicted spectral lines tend to be too narrow, reflecting insufficient Doppler broadening from the convective motions, while at the currently highest affordable...[Show more]
