Learning outcomes
|
The course aims to acquaint students with the physics of the solar corona, especially with the dynamical processes that take place there. The main focus will be on waves and oscillations in the solar corona, as one of the possible mechanisms of its heating. Another phenomenon that will be discussed is the reconnection of the magnetic field and other dynamic processes taking place in the solar atmosphere.
Students will be able to understand dynamical processes in solar plasma physics, mainly wave and oscillatory processes in the solar corona.
