FINE STRUCTURES AND OVERLYING LOOPS OF CONFINED SOLAR FLARES

Solar flares as cascades of reconnecting magnetic loops.

A model for the solar coronal magnetic field is proposed where multiple directed loops evolve in space and time. Loops injected at small scales are anchored by footpoints of opposite polarity moving randomly on a surface. Nearby footpoints of the same polarity aggregate, and loops can reconnect when they collide. This may trigger a cascade of further reconnection, representing a solar flare. Nu...

An Energy Release Mechanism of Current Loops in the Solar Atmosphere : Solar Flares and Corona Heating

A mechanism is proposed to account for the energy release by a bipolar current loop in the solar atmosphere. This mechanism is electromagnetic in nature and utilizes the non-zero J X B forces. No dissipation of the magnetic energy by resistivity, magnetic reconnection, or circuit interruption is required. From the observed fact that bipolar current loops do exist in quasi-equilibrium in the sol...

Solar flares and energetic particles.

Solar flares are now observed at all wavelengths from γ-rays to decametre radio waves. They are commonly associated with efficient production of energetic particles at all energies. These particles play a major role in the active Sun because they contain a large amount of the energy released during flares. Energetic electrons and ions interact with the solar atmosphere and produce high-energy X...
