The Role of Energy Diffusion in the Deposition of Energetic Electron Energy in Solar and Stellar Flares
Natasha L. S. Jeffrey, Eduard P. Kontar, Lyndsay Fletcher
During solar flares, a large fraction of the released magnetic energy is carried by energetic electrons that transfer and deposit energy in the Sun's atmosphere. Electron transport…
Fast Solar Image Classification Using Deep Learning and its Importance for Automation in Solar Physics
John A. Armstrong, Lyndsay Fletcher
The volume of data being collected in solar physics has exponentially increased over the past decade and with the introduction of the (D…
Spectral Evidence for Heating at Large Column Mass in Umbral Solar Flare Kernels I: IRIS NUV Spectra of the X1 Solar Flare of 2014 Oct 25
Adam F. Kowalski, Elizabeth Butler, Adrian N. Daw +5
The GOES X1 flare SOL2014-10-25T17:08:00 was a three-ribbon solar flare observed with IRIS in the near and far ultraviolet. One of the flare ribbons crossed a sunspot umbra, produc…
The plasmoid instability in a confined solar flare
David MacTaggart, Lyndsay Fletcher
Eruptive flares (EFs) are associated with erupting filaments and, in some models, filament eruption drives flare reconnection. Recently, however, observations of a confined flare (…
First Spectral Analysis of a Solar Plasma Eruption Using ALMA
Andrew S. Rodger, Nicolas Labrosse, Sven Wedemeyer +3
The aim of this study is to demonstrate how the logarithmic millimeter continuum gradient observed using the Atacama Large Millimeter/submillimeter Array (ALMA) may be used to esti…
Continuum emission enhancements and penumbral changes observed during flares by IRIS, ROSA, and Hinode
F. Zuccarello, S. L. Guglielmino, V. Capparelli +6
In this paper we describe observations acquired by satellite instruments (Hinode/SOT and IRIS) and ground-based telescopes (ROSA@DST) during two consecutive C7.0 and X1.6 flares oc…
