Measured energy exchange in coronal hole solar wind from its solar origins to the heliosphere
Yeimy J. Rivera, Alin R. Paraschiv, Samuel T. Badman +33
Coordinated ground- and space-based remote observations are used to provide a comprehensive, multi-perspective view of the solar atmosphere that we connect with in situ measurement…
Active nests at solar maximum: How nested flux emergence dominated flaring activity and structured the heliosphere
Adam J. Finley, Allan Sacha Brun, Antoine Strugarek +5
Multi-viewpoint observations from near-Earth satellites and ESA's Solar Orbiter enable a global view of the Sun. This continuous coverage is essential for characterising active nes…
Sulfur fractionation in coronal plumes as observed by Solar Orbiter/SPICE
Slimane Mzerguat, Miho Janvier, Eric Buchlin +4
Coronal plumes are bright, narrow structures rooted in coronal holes that contribute to the solar wind. Their composition, particularly elemental fractionation as a function of fir…
First coordinated observations between Solar Orbiter and the Daniel K. Inouye Solar Telescope
Krzysztof Barczynski, Miho Janvier, Chris J. Nelson +8
Solar Orbiter and the Daniel K. Inouye Solar Telescope (DKIST) are two of the newest facilities available to the solar physics community. The first coordinated observations of 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…
Solar Orbiter's 2024 Major Flare Campaigns: An Overview
Daniel F. Ryan, Laura A. Hayes, Hannah Collier +17
Solar Orbiter conducted a series of flare-optimised observing campaigns in 2024 utilising the Major Flare Solar Orbiter Observing Plan (SOOP). Dedicated observations were performed…
Analysis and modelling of recurrent solar flares observed with Hinode/EIS on March 9, 2012
V. Polito, G. Del Zanna, G. Valori +4
Three homologous C-class flares and one last M-class flare were observed by both the Solar Dynamics Observatory (SDO) and the Hinode EUV Imaging Spectrometer (EIS) in the AR 11429…
Evolution of Flare Ribbons, Electric Currents and Quasi-separatrix Layers During an X-class Flare
M. Janvier, A. Savcheva, E. Pariat +6
The standard model for eruptive flares has in the past few years been extended to 3D. It predicts typical J-shaped photospheric footprints of the coronal current layer, forming at…
Particle Acceleration In Plasmoid Ejections Derived From Radio Drifting Pulsating Structures
N. Nishizuka, M. Karlicky, M. Janvier +1
We report observations of slowly drifting pulsating structures (DPS) in the 0.8-4.5 GHz frequency range of the RT4 and RT5 radio spectrographs at Ondrejov observatory, between 2002…
Electric current in flares ribbons: observations and 3D standard model
Miho Janvier, G. Aulanier, V. Bommier +3
We present for the first time the evolution of the photospheric electric currents during an eruptive X-class flare, accurately predicted by the standard 3D flare model. We analyze…
