On the importance of Global Events in Destabilizations of the Solar Atmosphere
par Alan Title (Stanford, USA)
Lundi 6 février à 10h30 à l'IAS, bât. 121, salle 1-2-3
A large segment of solar research has focused on structures that give rise to violent events like flares and coronal mass ejections (CME's). This has placed emphasis on the development of active regions and filament channels with foci on energy build up and triggering. At the same time their has existed controversies about sympathetic flares, stealth CME's, and whether there can be CME's without flares.
The operation of the Solar Dynamic Observatory, which collects full Sun line-of-sight and vector magnetograms field maps as well as full Sum images in a range of wavelengths in the UV and UVE on a 12 second cadence 24/7, is now demonstrating that many violent solar events are connected. Recents simulations have suggest how the remote destabilizations occur. Maps of the Sun's magnetic topology show both the paths and the bounds of some of the instabilities.
It is clear we are in early stages of understanding of some of probably many mechanisms for destabilization. It is also clear that an understanding of the consequence of magnetic topologies are now and will in the future be a rich research topic.
Movies of solar events and corresponding simulations will be shown.
