We analyzed spatial and spectral characteristics of quasi-periodic pulses (QPP) for the limb flare on 18 August 2012, using new data from a complex of spectral and imaging instruments developed by the Siberian Solar Radio Telescope team and the Wind/Konus γ -ray spectrometer. A sequence of broadband pulses with periods of approximately ten seconds were observed in X-rays at energies...
We produce synthetic radio views of simulated flux ropes in the solar corona, where finite- β magnetohydrodynamic (MHD) simulations serve to mimic the flux-rope formation stages, as well as their stable endstates. These endstates represent twisted flux ropes where balancing Lorentz forces, gravity, and pressure gradients determine the full thermodynamic variation throughout the flux...
