Origins of Long Duration Gamma-Ray Emission at the Sun
Origins of Long Duration Gamma-Ray Emission at the Sun
Session ID#: 120562
Session Description:
Observations of gamma-ray emission lasting hours beyond other flare-associated electromagnetic signatures provide a test for models of particle acceleration and propagation at or near the Sun. Contributions based on data analysis, modelling and theory are solicited that address the following questions: Where and how are the energetic particles responsible for long duration gamma-ray emission accelerated? How are they able to propagate to the locations near the photosphere where gamma-rays are produced? Can experimental constraints inferred from gamma-ray emission and solar energetic particle measurements be reproduced by models and theory?
