Polarisation and source structure of solar stationary type IV radio bursts
Klein, Karl-Ludwig; Salas-Matamoros, Carolina
The reconfiguration of the magnetic field during and after a coronal mass ejection (CME) may be accompanied by radio emission from non-thermal electrons. In particular, stationary type IV bursts (also called storm continua) are emitted by electrons in closed magnetic configurations usually located in the wake of the outward-travelling CME. Althoug…
Electron acceleration and radio emission following the early interaction of two coronal mass ejections
Palmerio, E.; Magdalenić, J.; Kilpua, E. K. J. +6 more
Context. Coronal mass ejections (CMEs) are large eruptions of magnetised plasma from the Sun that are often accompanied by solar radio bursts produced by accelerated electrons.
Aims: A powerful source for accelerating electron beams are CME-driven shocks, however, there are other mechanisms capable of accelerating electrons during a CME erupt…
Extended radio emission associated with a breakout eruption from the back side of the Sun
Palmerio, E.; Kilpua, E. K. J.; Lynch, B. J. +1 more
Context. Coronal mass ejections (CMEs) on the Sun are the largest explosions in the Solar System that can drive powerful plasma shocks. The eruptions, shocks, and other processes associated to CMEs are efficient particle accelerators and the accelerated electrons in particular can produce radio bursts through the plasma emission mechanism.

Analyzing the propagation of EUV waves and their connection with type II radio bursts by combining numerical simulations and multi-instrument observations
Dolla, L.; Downs, C.; Marqué, C. +1 more
Context. EUV (EIT) waves are wavelike disturbances of enhanced extreme ultraviolet (EUV) emission that propagate away from an eruptive active region across the solar disk. Recent years have seen much debate over their nature, with three main interpretations: the fast-mode magneto-hydrodynamic (MHD) wave, the apparent wave (reconfiguration of the m…
