Dear colleagues!
We would like to raise attention to COSPAR Session E2.1 Session on «Magnetic Flux ropes in solar and stellar environments »
Deadline for abstract submission: 14 February 2020 - Looking forward to meet there!
COSPAR E2.1 Session: « Magnetic Flux Ropes in Solar and Stellar Environments »
Sydney, Australia, 15 – 22 August 2020
Rationale :
Magnetic flux bundles or ropes are the main building blocks forming active regions. Their destabilization can lead to the most violent events -- flares, coronal mass ejections (CMEs), and energetic particle events. After eruption, they are observed over a wide range of spatial scales throughout the heliosphere. Specific configurations of these structures can produce the strongest geomagnetic storms as they impact the Earth's magnetosphere. Stellar CMEs, which in analogy to solar CMEs could be caused by the eruption of large-scale flux ropes, may play an important role in mass and angular momentum losses of young Sun-like stars. It is also highly probable that observed superflares might be associated with very large stellar CMEs. Such powerful events may have significant implications for the physical conditions and the eventual habitability of orbiting exoplanets. The proposed event aims to shed light on the fundamental physics of different sets of flux rope structures, their genesis, escape of confinement, interaction, relevance for solar/stellar environments and plausible impact on their planets.
Four sessions are planned:
1. Solar and stellar dynamos, emergence of magnetic flux ropes, flux rope characteristics
2. The disruption and eruption of flux ropes, evolution of coronal mass ejections (CMEs)
3. Detection and models of flux rope evolution and interaction in the heliosphere
4. The stars: flares, stellar prominence, stellar coronal mass ejections: observations and theory
