Solar–Stellar Connection: X-Ray Flares to Energetic (E > 10 MeV) Particle Events
The Astrophysical Journal, 2023 Energetic particle environments are an important factor for the viability of life on exoplanets surrounding flare stars. In the heliosphere, large gradual solar energetic ( E > 10 MeV) particle (SEP) events are produced by shocks from fast coronal mass ...

The Efficiency of Electron Acceleration during the Impulsive Phase of a Solar Flare
The Astrophysical Journal Letters, 2023 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 settings) presents a major challenge.

Fine structure events in microwave emission during solar minimum
Solar-Terrestrial Physics, 2019 The solar minimum is a period with a relatively smaller number of sunspots and solar eruptions, and has been less studied before. Since the radio signal rapidly responds to the change of solar plasma and magnetic field, we perform a comprehensive ...

Sawtooth oscillations in solar flare radio emission [PDF]
Astronomy & Astrophysics, 2001 For the first time, we found a spectral fine structure of solar meter wave radio burst emission which can be due to sawtooth oscillations in the hot flare plasma. This finding newly underlines an analogy between coronal and laboratory plasma processes. The sawteeth occur during the impulsive flare phase hard X-ray emission and consist of a sequence of ...

Observation of Six Pre-Flare VLP Pulsations in Solar Corona [PDF]
Iranian Journal of Astronomy and Astrophysics, 2023 Solar flares are sudden bursts in the solar atmosphere, which emit from radio wavelengths to gamma rays, and according to their energy, are classified into different classes (A, B, C, M, and X, respectively).

Solar Radio Bursts Associated with In Situ Detected Energetic Electrons in Solar Cycles 23 and 24
Universe, 2022 The first comprehensive analysis between the in situ detected solar energetic electrons (SEEs) from ACE/EPAM satellite and remotely observed radio signatures in solar cycles (SCs) 23 and 24 (1997–2019) is presented.

Radio Behavior of Solar Post-Flare Loops [PDF]
Proceedings of the International Astronomical Union, 2006 The spectral and source characteristics of a complex radio burst observed with the spectrometers of China and the Nobeyama Radio Heliograph are analyzed. This burst presents two separate burst peaks occurred in different frequency range (broad-band microwave and narrow-band decimeter wavelengths). We stress that the late phase radio bursts in decimeter

A deep learning method for the recognition of solar radio burst spectrum [PDF]
PeerJ Computer Science, 2022 Solar radiation is the excitation source that affects the weather in the atmosphere of the earth, and some solar activities such as flares and coronal mass ejections are often accompanied by radio bursts. The spectrum of solar radio bursts is helpful for
