Probing the properties of active regions in the solar interface region using full-disk spectroheliograms
Éabha Power, David M. Long, Teodora Mihailescu +1
The composition of plasma in the solar corona is characterised by the First Ionisation Potential (FIP) bias, and is thought to be the result of a ponderomotive force acting in the…
Spatiotemporal evolution of UV pulsations and their connection to 3D magnetic reconnection and particle acceleration
Stefan Purkhart, Hannah Collier, Laura A. Hayes +3
Quasi-periodic pulsations (QPPs) are a common feature of impulsive solar flare emissions, yet their driving mechanism(s) remain unresolved. We study long-period (3.4 min) QPPs in t…
Systematic non-thermal velocity increase preceding soft X-ray flare onset: A large-scale Hinode/EIS study
Andy S. H. To, Abigail Burden, Deborah Baker +12
Non-thermal velocities, derived from spectral line broadening, can provide crucial insights into plasma dynamics before and during solar flares. To systematically study the pre-fla…
Probing progression of heating through the lower flare atmosphere via high-cadence IRIS spectroscopy
Juraj Lörinčík, 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…
Quasi-Periodic Pulsations in Ionospheric TEC Synchronized with Solar Flare EUV Emission
Aisling N. O'Hare, Susanna Bekker, Laura A. Hayes +1
The extreme ultraviolet (EUV) and X-ray radiation emitted during solar flares has been shown to significantly increase the electron density of the Earth's ionosphere. During flares…
Bursty acceleration and 3D trajectories of electrons in a solar flare
Shilpi Bhunia, Laura A. Hayes, Karl Ludwig Klein +3
During a solar flare, electrons are accelerated to non-thermal energies as a result of magnetic reconnection. These electrons then propagate upwards and downwards from the energy r…
X-ray and Spectral UV Observations of Periodic Pulsations in a Solar Flare Fan/Looptop
Ryan J. French, Laura A. Hayes, Maria D. Kazachenko +3
We present simultaneous X-ray and spectral ultraviolet (UV) observations of strikingly-coherent oscillations in emission from a coronal looptop and fan structure, during the impuls…
Spatially Resolved Plasma Composition Evolution in a Solar Flare -- The Effect of Reconnection Outflow
Andy S. H. To, David H. Brooks, Shinsuke Imada +6
Solar flares exhibit complex variations in elemental abundances compared to photospheric values. We examine the spatial and temporal evolution of coronal abundances in the X8.2 fla…
