Coronal Mass Ejections and Solar Gamma-ray Emission

Explore the fascinating world of sustained gamma-ray emission (SGRE) from the Sun in this comprehensive seminar. Delve into the characteristics of SGRE, its discovery, and the significant advancements made possible by the Fermi satellite's Large Area Telescope. Examine the statistical properties of SGRE events and their associations with solar eruptive phenomena. Gain insights into the origin of sub-300 MeV protons and their interactions with the solar chromosphere, leading to the observed gamma-rays. Investigate the connections between SGRE events and various solar phenomena, including X-ray class M and X flares, large solar energetic particle events, interplanetary type II radio bursts, and superfast coronal mass ejections. Understand the relationships between these eruptive phenomena and the mechanisms behind particle acceleration in both CME-driven shocks and flare reconnection regions.
