KUL/CmPA Seminar: Magnetohydrodynamic modelling of Alfvén waves in the solar corona

Seminar by Chaitanya Sishtla (University of Helsinki)

Title: Magnetohydrodynamic modelling of Alfvén waves in the solar corona


Alfvén waves are ubiquitous in the solar wind. Their nonlinear interactions and eventual turbulent cascade result in an important heating mechanism that accelerates the solar wind. These waves are generated at the photosphere and propagate throughout the heliosphere. They are processed and interact with plasma structures like shocks and coronal mass ejections (CME). However, the non-linear nature of the wave-wave and wave-plasma interactions makes studying the propagation of these waves challenging and complex to assess. In this seminar, I will present a magnetohydrodynamic approach to modelling Alfvén waves and studying their interactions with CMEs in the solar corona. The results presented in the seminar will have an emphasis on the multi-step processes involved in the propagation, reflection, and decay mechanisms of these waves.
