Automatic detection of Flare Ribbon Fine Structures as Proxies for Plasmoid Dynamics in Flare Reconnection
Georgios Chouliaras, Peter F. Wyper, Joel T. Dahlin +1
Flare ribbons often display fine structures along their fronts that are commonly interpreted as signatures of intermittent reconnection dynamics including plasmoid formation in the…
Extremely energetic EUV late phase of a pair of C-class flares caused by a non-eruptive sigmoid
Ya Wang, Sargam M. Mulay, Lyndsay Fletcher
The EUV late phase is the second increase of the irradiance of the warm coronal lines during solar flares, and has a crucial impact on the Earth's ionosphere. In this paper, we rep…
Magnetic Dip Found in a Quiescent Prominence Foot via Observation and Simulation
Huadong Chen, Chun Xia, Suli Ma +8
Solar prominences (or filaments) are cooler and denser plasma suspended in the much hotter and rarefied solar corona. When viewed on the solar disc filament barbs or feet protrude…
High-resolution observational analysis of flare ribbon fine structures
Jonas Thoen Faber, Reetika Joshi, Luc Rouppe van der Voort +4
Context. Since the mechanism of energy release from solar flares is still not fully understood, the study of fine-scale features developing during flares becomes important for prog…
Simultaneous Eruption and Shrinkage of Pre-existing Flare Loops during a Subsequent Solar Eruption
Huadong Chen, Lyndsay Fletcher, Guiping Zhou +6
We investigated two consecutive solar eruption events in the solar active region (AR) 12994 at the solar eastern limb on 2022 April 15. We found that the flare loops formed by the…
Photospheric signatures of CME onset
Aslam Ottupara, David MacTaggart, Tom Williams +2
Coronal mass ejections (CMEs) are solar eruptions that involve large-scale changes to the magnetic topology of an active region. There exists a range of models for CME onset which…
An impulsive geomagnetic effect from an early-impulsive flare
Hugh S. Hudson, Edward. W. Cliver, Lyndsay Fletcher +6
The geomagnetic "solar flare effect" (SFE) results from excess ionization in the Earth's ionosphere, famously first detected at the time of the Carrington flare in 1859. This indir…
Precise timing of solar flare footpoint sources from mid-infrared observations
Paulo J. A. Simões, Lyndsay Fletcher, Hugh S. Hudson +3
Solar flares are powerful particle accelerators, and in the accepted standard flare model most of the flare energy is transported from a coronal energy-release region by accelerate…
Hydrogen recombination continuum as the radiative model for stellar optical flares
Paulo J. A. Simões, Alexandre Araújo, Adriana Válio +1
The study of stellar flares has increased with new observations from CoRoT, Kepler, and TESS satellites, revealing the broadband visible emission from these events. Typically, stel…
Enhanced three-minute oscillation above a sunspot during a solar flare
Ya Wang, Lyndsay Fletcher, Sargam Mulay +2
Three-minute oscillations are a common phenomenon in the solar chromosphere above a sunspot. Oscillations can be affected by the energy release process related to solar flares. In…
Behaviour of molecular hydrogen emission in three solar flares
Sargam M. Mulay, Lyndsay Fletcher, Hugh Hudson +1
We have systematically investigated ultraviolet (UV) emission from molecular hydrogen (H) using the Interface Region Imaging Spectrometer (IRIS), during three X-ray flares of…
On the Importance of Ca II Photoionisation by the Hydrogen Lyman Transitions in Solar Flare Models
Christopher M. J. Osborne, Petr Heinzel, Jana Kašparová +1
The forward fitting of solar flare observations with radiation-hydrodynamic simulations is a common technique for learning about energy deposition and atmospheric evolution during…
Arcade Implosion Caused by a Filament Eruption in a Flare
Juntao Wang, P. J. A. Simoes, L. Fletcher +3
Coronal implosions - the convergence motion of plasmas and entrained magnetic field in the corona due to a reduction in magnetic pressure - can help to locate and track sites of ma…
Halpha line profile asymmetries and the chromospheric flare velocity field
D. Kuridze, M. Mathioudakis, P. J. A. Simões +9
The asymmetries observed in the line profiles of solar flares can provide important diagnostics of the properties and dynamics of the flaring atmosphere. In this paper the evolutio…
Charge-exchange limits on low-energy alpha-particle fluxes in solar flares
Hugh Hudson, Lyndsay Fletcher, Alec MacKinnon +1
This paper reports on a search for flare emission via charge-exchange radiation in the wings of the Lyman-alpha line of He ii at 304 A, as originally suggested for hydrogen by Orra…
Splinter Session "Solar and Stellar Flares"
L. Fletcher, H. S. Hudson, G. Cauzzi +8
This summary reports on papers presented at the Cool Stars-16 meeting in the splinter session "Solar and Stellar flares." Although many topics were discussed, the main themes were…
Break up of returning plasma after the 7 June 2011 filament eruption by Rayleigh-Taylor instabilities
D. E. Innes, R. H. Cameron, L. Fletcher +2
A prominence eruption on 7 June 2011 produced spectacular curtains of plasma falling through the lower corona. At the solar surface they created an incredible display of extreme ul…
Observations of conduction driven evaporation in the early rise phase of solar flares
M. Battaglia, L. Fletcher, A. O. Benz
In the classical flare picture, hard X-ray emission from the chromosphere is succeeded by soft-X-ray emission from hot plasma in the flare loop, the soft X-ray emission being a dir…
Field-guided proton acceleration at reconnecting X-points in flares
B. Hamilton, K. G. McClements, L. Fletcher +1
An explicitly energy-conserving full orbit code CUEBIT, developed originally to describe energetic particle effects in laboratory fusion experiments, has been applied to the proble…
