E2.3 The Life Cycle of Prominences: New Insights from Solar Orbiter and the Multi-messenger Era
Nous avons le plaisir de vous inviter à soumettre un abstract pour cette session du COSPAR, qui se tiendra à Florence, en Italie, du 1er au 9 août 2026.
Cette session offrira l’occasion de passer en revue les avancées récentes sur les protubérances solaires et stellaires en tant que laboratoires pour l’étude de plasmas froids partiellement ionisés. En tirant parti des observations multi-points de vue de Solar Orbiter et des installations au sol, nous aborderons la formation et la stabilisation des protubérances. Nous encourageons les contributions portant sur leur structuration et leur interaction avec la couronne, à travers des observations, des simulations numériques, la sismologie, la MHD et la modélisation du transfert radiatif.
Orateurs/ices invités confirmés: Moira Jardine (UK), Reetika Joshi (USA), Sonja Jejčič (Slovenia), Valeriia Liakh (Norway). Qinming Zhang (China), Veronica Jerčić (USA), Qingmin Zhang (Purple Mountain Observatory, CH), Veronika Jerčić (NASA Goddard Space Flight Center, USA).

E2.4 Solar jets, CMEs, and Associated EUV Waves
Solar jets, coronal mass ejections (CMEs) and the extreme ultraviolet (EUV) waves are interesting and important phenomena observed on the sun. Investigation of their nature and their connection requires the synergy of observations from different wavelengths. Recently, we have several solar space missions in operation, such as Solar Dynamics Observatory, Solar Orbiter, CHASE, ASO-S, Aditya-L1, which provide the golden opportunity to study solar eruptions. In order to understand the physical cause among solar jets, CMEs, and associated EUV waves, we plan to bring together the experts studying all aspects of these phenomena.
We will focus on these topics:
- Multi-scale solar jets, energy sources, triggering and driving mechanisms of solar jets.
- High spatio-temporal resolution observations of EUV waves and associated jets and CMEs.
