SH: Large amplitude oscillations in solar filaments – Cécere

April 22 @ 12:15 pm 12:30 pm CMT

It has been known that solar filaments show oscillations. These types of motions are normally triggered by nearby flares or jets, EIT waves and Moreton waves. In this work we analyse how coronal waves are able to excite filament oscillations through 2.5 MHD simulations. We find correlations between height, size and mass with period, amplitudes and damping times. We also find that magnetic tension is the main restoring force exerted on the filament.
