abstract:
Abstract: The outer atmosphere of the Sun is a magnetically-dominated
environment. The magnetic field determines the transport, storage and
dissipation of energy, in fairly steady ways (coronal heating, solar
wind acceleration) but also in abrupt and impulsive events called solar
flares. Solar flares represent the rapid conversion of energy in the
magnetically stressed corona into plasma heating and the KE of
accelerated particles and mass motions. Flares are now observed in
exquisite detail with imaging and spectroscopy across the
electromagnetic spectrum, allowing increasingly meaningful comparisons
with detailed theory. In this talk I will give a general overview of
recent flare observations and the framework in which they are
interpreted, before focusing on one aspect of flare physics, namely the
need to rapidly transport energy through the corona and accelerate
particles. I will also place our knowledge of solar flares and their
effect on Earth in the context of what we are learning about stellar
flares and their possible impact on their planetary systems.
