Uncovering the heterogeneity of a solar flare mechanism with mixture models

Frontiers in Astronomy and Space Sciences
The physics of solar flares occurring on the Sun is highly complex and far from fully understood. However, observations show that solar eruptions are associated with the intense kilogauss fields of active regions, where free energies are stored with ...

X-ray imaging of flare loops and coronal arches [PDF]

HXIS (Hard X-ray Imaging Spectrometer) results related to preflare, flare-decay, and post-flare phases in the solar corona are summarized. Particularly discussed are miniflares, long-lived X-ray enhancements along filament channels, flare precursors ...

Can Solar Limb Flare Prediction Be Properly Made by Extreme-ultraviolet Intensities?

The Astrophysical Journal Letters
We address the question of whether the solar limb flare prediction can be properly made by EUV intensity, which has less projection effects than solar white light and magnetogram data.

Dynamics of the Coronal Magnetic Field in the 2022 October 2 X-class Flare

The Astrophysical Journal
Solar flares are driven by the release of free magnetic energy and are often associated with the restructurization of the magnetic field topology. Yet, observations of the evolving magnetic field in the flaring volume are limited to very few cases ...

ALEXIS: Recreating the X-Ray Emission from the Full Solar Disk as a Linear Combination of Discrete Regions in the Extreme Ultraviolet and Soft X-Rays

The Astrophysical Journal Supplement Series
Despite a wealth of multiwavelength, spatially resolved, time-domain solar activity data, an accurate and complete temporospatial solar flare census is unavailable, which impedes our understanding of the physics of flare production.
