KU Leuven/CmPA Seminar: Flux rope deflections due to coronal holes and pseudostreamers

KU Leuven Centre for mathematical Plasma-Astrophysics Seminar

Title: Flux rope deflections due to coronal holes and pseudostreamers

Speaker: Abril Sahade from Universidad Nacional de Córdoba


Understanding the causes of coronal mass ejection (CME) deflections is essential for space weather forecasting. We perform ideal magnetohydrodynamical simulations that emulate the early ascent of a flux rope (FR) in the presence of a coronal hole (CH) or a pseudostreamer (PS) and study the effects on the trajectories of CMEs produced by these magnetic structures. We find that the presence of magnetic energy null points plays a crucial role in the initial deflection in both scenarios. During the seminar, we present specific results for each interaction and the analysis of an observational event with a peculiar behaviour.


The seminars are in hybrid mode, you can follow in person in room 200B 00.07 or online  at the (permanent) link:
