The Astrophysical JournalThis study is based on proton flux data from ESA’s Solar Energetic Particle Environment Modeling database, analyzing solar energetic particle (SEP) events observed near Earth from 1976 to 2017. We have matched these events with corresponding solar flares

The Astrophysical Journal LettersAbstract This Letter proposes that the ion temperature is several times the local electron temperature in the hot onset phase and in the above-the-loop region of solar flares. The Letter considers: the evidence of spectral line Doppler widths (“nonthermal” broadening); evidence for “universal” ion and electron temperature increase ...

A Study of Photospheric Vector Magnetic Field Changes During Solar Flares [PDF]
, 2016 . Large amounts of energy are released when magnetic field lines reconnect in the corona during solar flares. Observations have found both transient and irreversible changes in the photospheric magnetic fields during flares, but their origins and ...

Solar Flares Triggered by a Filament Peeling Process Revealed by High-resolution GST Hα Observations
The Astrophysical Journal LettersThe dynamic structures of solar filaments prior to solar flares provide important physical clues about the onset of solar eruptions. Observations of those structures under subarcsecond resolution with high cadence are rare.

The Role of Reconnection at Magnetic Separators in Complex Solar Flare Ribbons
The Astrophysical JournalSolar flare ribbons, manifesting as transient brightenings in the chromosphere, are believed to trace the footpoints of magnetic field lines reconnecting higher in the solar atmosphere.

Solar flares - Magnetohydrodynamic instabilities
, 1981 It is pointed out that most solar flares are either simple-loop (or compact) flares or two-ribbon flares. A single loop brightens and decays without moving, whereas the appearance of the two-ribbon type involves the eruption of a magnetic arcade.
