Solar Orbiter observations of solar energetic electron events associated with hard microflares
Diane Mittaine, Andrea Francesco Battaglia, Laura RodrÃguez-GarcÃa +4
Generally, large solar flares accelerate electrons to high energies more efficiently than microflares. However, some microflares, known as hard microflares (HMFs), also produce hig…
ZIMPOL detects scattering polarization in He I D during a solar flare
Francesco Vitali, Andrea Francesco Battaglia, Luca Belluzzi +5
Spectropolarimetric observations of solar flares in the He I D line at 5876 Ã are extremely rare, and their diagnostic potential remains largely unexplored. We report the first…
Unveiling Spatiotemporal Properties of the Quasi-periodic Pulsations in the Balmer Continuum at 3600 Ã in an X-class Solar White-light Flare
De-Chao Song, Marie Dominique, Ivan Zimovets +11
Quasi-periodic pulsations (QPPs) in the Balmer continuum of solar white-light flares (WLFs) are rarely reported, and accurately pinpointing the spatial source of flaring QPPs remai…
New insights into the proton precipitation sites in solar flares
Andrea Francesco Battaglia, Säm Krucker
The Reuven Ramaty High Energy Solar Spectrocopy Imager (RHESSI) -ray observations of the extraordinary GOES X25 flare SOL2003-10-28T11:10 are revisited to investigate previousl…
The observational evidence that all microflares that accelerate electrons to high energies are rooted in sunspots
Andrea Francesco Battaglia, Säm Krucker, Astrid M. Veronig +6
In general, large solar flares are more efficient at accelerating high-energy electrons than microflares. Nonetheless, we sometimes observe microflares that accelerate electrons to…
A Joint Microwave and Hard X-Ray Study Towards Understanding the Transport of Accelerated Electrons during an Eruptive Solar Flare
Surajit Mondal, Andrea F. Battaglia, Bin Chen +1
The standard flare model, despite its success, is limited in comprehensively explaining the various processes involving nonthermal particles. One such missing ingredient is a detai…
