The energetic atmosphere of the Sun
Sven Wedemeyer, Mats Kirkaune, Miroslav Barta +16
Understanding the mechanisms that heat the Sun's chromosphere and corona to temperatures far exceeding those of the solar photosphere below remains one of the central challenges in…
Solar Radio Burst Fine Structures
Eduard Kontar, Daniel Clarkson, Hamish Reid +5
Solar radio bursts exhibit intricate variability in time, space, and frequency, often displaying a rich variety of fine frequency-time structures such as spikes, drift pairs, stria…
Millimeter-Wavelength Observations of the Active Sun: Unveiling the Origins of Space Weather
Sven Wedemeyer, Stefaan Poedts, Stanislav Gunár +15
Societal dependence on space-based services demands major advances in predicting the impacts of eruptive solar events. Millimeter-wavelength observations offer uniquely direct acce…
Energy budget in the 2017-09-07 "cold" solar flare
Gregory D. Fleishman, Galina G. Motorina, Sijie Yu +1
A subclass of early impulsive solar flares, cold flares, was proposed to represent a clean case, where the release of the free magnetic energy (almost) entirely goes to acceleratio…
AtLAST Science Overview Report
Mark Booth, Pamela Klaassen, Claudia Cicone +81
Submillimeter and millimeter wavelengths provide a unique view of the Universe, from the gas and dust that fills and surrounds galaxies to the chromosphere of our own Sun. Current…
Atacama Large Aperture Submillimeter Telescope (AtLAST) Science: Solar and stellar observations
Sven Wedemeyer, Miroslav Barta, Roman Brajsa +35
Observations at (sub-)millimeter wavelengths offer a complementary perspective on our Sun and other stars, offering significant insights into both the thermal and magnetic composit…
Cold Solar Flares I. Microwave Domain
Alexandra L. Lysenko, Stephen M. White, Dmitry A. Zhdanov +4
We identify a set of ~100 "cold" solar flares and perform a statistical analysis of them in the microwave range. Cold flares are characterized by a weak thermal response relative t…
Data-constrained 3D modeling of a solar flare evolution: acceleration, transport, heating, and energy budget
Gregory D. Fleishman, Gelu M. Nita, Galina G. Motorina
Solar flares are driven by release of the free magnetic energy and its conversion to other forms of energy -- kinetic, thermal, and nonthermal. Quantification of partitions between…
Magnetic Energy Powers the Corona: How We Can Understand its 3D Storage & Release
Amir Caspi, Daniel B. Seaton, Roberto Casini +12
The coronal magnetic field is the prime driver behind many as-yet unsolved mysteries: solar eruptions, coronal heating, and the solar wind, to name a few. It is, however, still poo…
Improving Multi-Dimensional Data Formats, Access, and Assimilation Tools for the Twenty-First Century
Daniel B. Seaton, Amir Caspi, Roberto Casini +12
Heliophysics image data largely relies on a forty-year-old ecosystem built on the venerable Flexible Image Transport System (FITS) data standard. While many in situ measurements us…
COMPLETE: A flagship mission for complete understanding of 3D coronal magnetic energy release
Amir Caspi, Daniel B. Seaton, Roberto Casini +12
COMPLETE is a flagship mission concept combining broadband spectroscopic imaging and comprehensive magnetography from multiple viewpoints around the Sun to enable tomographic recon…
The efficiency of electron acceleration during the impulsive phase of a solar flare
Eduard P. Kontar, A. Gordon Emslie, Galina G. Motorina +1
Solar flares are known to be prolific electron accelerators, yet identifying the mechanism(s) for such efficient electron acceleration in solar flare (and similar astrophysical set…
Energy budget of plasma motions, heating, and electron acceleration in a three-loop solar flare
Gregory D. Fleishman, Lucia Kleint, Galina G. Motorina +2
Non-potential magnetic energy promptly released in solar flares is converted to other forms of energy. This may include nonthermal energy of flare-accelerated particles, thermal en…
Radio Echo in the Turbulent Corona and Simulations of Solar Drift-Pair Radio Bursts
Alexey A. Kuznetsov, Nicolina Chrysaphi, Eduard P. Kontar +1
Drift-pair bursts are an unusual type of solar low-frequency radio emission, which appear in the dynamic spectra as two parallel drifting bright stripes separated in time. Recent i…
Spatio-temporal energy partitioning in a non-thermally dominated two-loop solar flare
Galina G. Motorina, Gregory D. Fleishman, Eduard P. Kontar
Solar flares show remarkable variety of the energy partitioning between thermal and nonthermal components. Those with a prominent nonthermal component but only a modest thermal one…
Electron distribution and energy release in magnetic reconnection outflow regions during the pre-impulsive phase of a solar flare
Marina Battaglia, Eduard P. Kontar, Galina Motorina
We present observations of electron energization in magnetic reconnection outflows during the pre-impulsive phase of solar flare SOL2012-07-19T05:58. During a time-interval of abou…
Multi-thermal representation of the kappa-distribution of solar flare electrons and application to simultaneous X-ray and EUV observations
Marina Battaglia, Galina Motorina, Eduard P. Kontar
Acceleration of particles and plasma heating is one of the fundamental problems in solar flare physics. An accurate determination of the spectrum of flare energized electrons over…
