Tracing the Heliospheric Magnetic Field via Anisotropic Radio-Wave Scattering
Daniel L. Clarkson, Eduard P. Kontar, Nicolina Chrysaphi +4
Astrophysical radio sources are embedded in turbulent magnetised environments. In the 1 MHz sky, solar radio bursts are the brightest sources, produced by electrons travelling alon…
An Anisotropic Density Turbulence Model from the Sun to 1 au Derived From Radio Observations
Eduard P. Kontar, A. Gordon Emslie, Daniel L. Clarkson +5
Solar radio bursts are strongly affected by radio-wave scattering on density inhomogeneities, changing their observed time characteristics, sizes, and positions. The same turbulenc…
The efficiency of electron acceleration during the impulsive phase of a solar flare
Eduard P. Kontar, A. Gordon Emslie, Galina G. Motorina +1
Solar flares are known to be prolific electron accelerators, yet identifying the mechanism(s) for such efficient electron acceleration in solar flare (and similar astrophysical set…
The data center for the Spectrometer and Telescope for Imaging X-rays (STIX) onboard Solar Orbiter
Hualin Xiao, Shane Maloney, Säm Krucker +12
The Spectrometer and Telescope for Imaging X-rays (STIX) on board Solar Orbiter observes solar X-ray emission in the range of 4 – 150 keV and produces spectra and images of s…
Solar flare hard X-rays from the anchor points of an eruptive filament
Muriel Zoë Stiefel, Andrea Francesco Battaglia, Krzysztof Barczynski +7
Context. We present an analysis of a GOES M1.8 flare with excellent observational coverage in UV, EUV, and X-ray, including observations from the instruments IRIS, SDO with AIA, Hi…
Temperature and Differential Emission Measure Profiles in Turbulent Solar Active Region Loops
A. Gordon Emslie, Stephen J. Bradshaw
We examine the temperature structure of static coronal active region loops in regimes where thermal conductive transport is driven by Coulomb collisions, by turbulent scattering, o…
