We analyse quasi-periodic pulsations (QPPs) which happened about 25 minutes after an M4-class solar flare on 5 September 2017. The QPP event was manifested as a bursty rapid enhancement of the flare microwave and decimeter radio emission, with almost no signatures pronounced in soft X-rays in comparison with the background flux caused by the decay phase of the preceding M4 flare. Simultaneous...
Fast electron streams in the plasma of the solar corona propagating along the magnetic field lines are able to drive Langmuir turbulence. The further resonant interaction of electrons with turbulent spectrum can lead to acceleration to high energies forming tails of a suprathermal distribution. Similar phenomena are observed in experiments at open magnetic traps with electron beams. An open...
Photospheric motions drive the twisting and braiding of coronal magnetic field confining loop plasma. Magnetic stress eventually leads to reconnection and conversion of magnetic energy into heat through current dissipation. We model this process by fully 3D MHD loop simulations and derive observables that directly track the dissipating currents, therefore providing evidence for the structuring...
The proton energy spectra of 23 Energetic Storm Particle events, occurring either in association with (16 events) or in absence of (7 events) Solar Energetic Particles, are investigated by using data from particle instruments aboard STEREO A in the energy range from 84.1 keV to 100 MeV. For the SEP events at quasi-perpendicular shocks, the Weibull distribution provides good fits to the...
The launch of the Solar Orbiter mission has motivated an intensification of the science activities in preparation for the exploitation of the data. For the METIS coronagraph, these activities are coordinated by topical teams, working on different physical problems. Here we present the activities carried out so far by the topical team on Coronal Shocks and Particle Acceleration. This team is...
