Energy Budget of Plasma Motions, Heating, and Electron Acceleration in a Three-loop Solar Flare
Original language description
Our article, based on multiwavelength data and 3D modeling, we quantify the energy partitioning and spatial distribution in the well-observed SOL2014-02-16T064620 solar flare of class C1.5. Nonthermal emission of this flare displayed a simple impulsive single-spike light curve lasting about 20 s. In contrast, the thermal emission demonstrated at least three distinct heating episodes, only one of which was associated with the nonthermal component. The flare was accompanied by upflows and downflows and substantial turbulent velocities. The results of our analysis suggest that (i) the flare occurs in a multiloop system that included at least three distinct flux tubes (ii) the released magnetic energy is divided unevenly between the thermal and nonthermal components in these loops (iii) only one of these three flaring loops contains an energetically important amount of nonthermal electrons, while two other loops remain thermal (iv) the amounts of direct plasma heating and that due to nonthermal electron loss are comparable and (v) the kinetic energy in the flare footpoints constitutes only a minor fraction compared with the thermal and nonthermal energies.
