Plasma Heating and Energization in Hot-Onset Flare Precursor Events
H. Da, J. F. Drake, M. Swisdak
Recent observations of solar flares have revealed a distinct 'hot onset' phase preceding the impulsive phase, characterized by elevated plasma temperature (>10 MK), a steady increa…

Wave Generation by Flare-Accelerated Ions and Implications for 3He Acceleration
A. Fitzmaurice, J. F. Drake, M. Swisdak
The waves generated by high-energy proton and alpha particles streaming from solar flares into regions of colder plasma are explored using particle-in-cell simulations. Initial dis…

Magnetic Energy Powers the Corona: How We Can Understand its 3D Storage & Release
Amir Caspi, Daniel B. Seaton, Roberto Casini +12
The coronal magnetic field is the prime driver behind many as-yet unsolved mysteries: solar eruptions, coronal heating, and the solar wind, to name a few. It is, however, still poo…
