Study on chromospheric heating by fast and slow MHD waves using realistic simulation

The problem how to heat the solar chromosphere is still under debate especially in magnetic chromosphere. MHD waves are considered as important energy transporter and make contribution to chromospheric heating. Previous researches usually discuss propagation of MHD waves in the chromosphere with great detail but the setting of flux tube and wave generation is artificial. There are also studies by realistic simulation but they are used for comparison with observations without discussing detail physical processes. In our study. we use 2-dimensional realistic MHD simulation. We separate fast and slow MHD waves by identifying the relation between directions of magnetic field and velocity. we further estimate the contribution to radiative loss by slow wave and fast wave. We conclude that fast wave plays a more dominant role in heating the magnetic chromosphere.
