Nonthermal line broadening at solar flare footpoints is primarily field-aligned
Andy S. H. To, Alexander J. B. Russell
Magnetic reconnection powers solar and stellar flares, but a full understanding of how the released energy is transported and converted within the solar atmosphere remains elusive.…
Eigenmode initialisation of 2D (magneto)hydrodynamic simulations
Jordi De Jonghe, Alexander J. B. Russell
The early evolution of unstable hydrodynamic and magnetohydrodynamic equilibria is often governed by a few dominant linear eigenmodes. We investigate whether initialising a simulat…
Solar Flare Ion Temperatures
Alexander J. B. Russell, Vanessa Polito, Paola Testa +2
This paper proposes that the ion temperature is several times the local electron temperature in the hot onset phase and at the above-the-loop region of solar flares. The paper cons…
Ion-rich acceleration during an eruptive flux rope event in a multiple null-point configuration
Melissa Pesce-Rollins, Alexander MacKinnon, Karl-Ludwig Klein +8
We report on the -ray emission above 100~MeV from the GOES M3.3 flare SOL2012-06-03. The hard X-ray (HXR) and microwave emissions have typical time profiles with a fast rise to…
Probing progression of heating through the lower flare atmosphere via high-cadence IRIS spectroscopy
Juraj LörinÄÃk, Vanessa Polito, Graham S. Kerr +2
Recent high-cadence flare campaigns by the Interface Region Imaging Spectrograph (IRIS) have offered new opportunities to study rapid processes characteristic of flare energy relea…
Flux-Rope Mediated Turbulent Magnetic Reconnection
Alexander J. B. Russell
We present a new model of magnetic reconnection in the presence of turbulence, applicable when the magnetic helicity is non-zero. The new model differs from the Lazarian-Vishniac t…
