Abstract:

So far perhaps only the structures in the solar surface and atmosphere can be observed in detail. Abundant observations the past decades have reveal interactions between solar plasma and magnetic field, which pose a high bar for theoretical models. Radiative magentohydrodynamic simulations account for the energy transport by radiation and conduction processes as in the real solar atmosphere with the basic MHD equations, such that the plasma properties in the numerical model is quantitatively consistent with the real Sun. Such method stands for the state-of-the-art for studying solar magnetic flux emergence, coronal heating, and solar eruptions. This presentation will demonstrate examples of realistic simulations that can be quantitatively compared with solar observations and our recent attempt of reproducing an emerging solar active region in a one-to-one manner using RMHD simulation with a data-driven boundary.
