| Abstract: | The important achievements and progress of the heating mechanisms of the star chromospheres and coronae in recent years are briefly reviewed in this paper.Various kinds of mechanisms have been proposed to accomplish the heating processes in the start atmosphere,and there are different mechanisms in the regions with or without magnetic field. In the region without magnetic field,the main heating mechanism is shock dissipation from acoustic waves which generated by the motion of turbulent in photosphere.The e... |
