Spectral Analysis of Solar Radio Type III Bursts from 20 kHz to 410 MHz
The Astrophysical Journal, 2022 We present the statistical analysis of the spectral response of solar radio type III bursts over the wide frequency range between 20 kHz and 410 MHz. For this purpose, we have used observations that were carried out using both spaced-based (Wind/Waves ...

Solar energetic particles and radio burst emission
Journal of Space Weather and Space Climate, 2017 We present a statistical study on the observed solar radio burst emission associated with the origin of in situ detected solar energetic particles. Several proton event catalogs in the period 1996–2016 are used.

Isolated Sunspot with a Dark Patch in the Coronal Emission
Open Astronomy, 2012 On the base of the 17 GHz radio maps of the Sun taken with the Nobeyama Radio Heliograph we estimate plasma parameters in the specific region of the sunspot atmosphere in the active region AR 11312.

Characterizing the Spectral Structure of Weak Impulsive Narrowband Quiet Sun Emissions
The Astrophysical Journal, 2023 Weak Impulsive Narrowband Quiet Sun Emissions (WINQSEs) are a newly discovered class of radio emission from the solar corona. These emissions are characterized by their extremely impulsive, narrowband, and ubiquitous nature.

Fibre structure of decametric type II radio bursts as a manifestation of emission propagation effects in a disturbed near-solar plasma [PDF]
Annales Geophysicae, 2009 This paper addresses the fine structure of solar decametric type II radio bursts in the form of drifting narrowband fibres on the dynamic spectrum. Observations show that this structure appears in those events where there is a coronal mass ejection ...

The Astrophysical Journal Letters, 2023 Magnetohydrodynamic (MHD) waves are often invoked to interpret quasiperiodic pulsations (QPPs) in solar flares. We study the response of a straight flare loop to a kink-like velocity perturbation using three-dimensional MHD simulations and forward model ...

A Type II Radio Burst Driven by a Blowout Jet on the Sun
The Astrophysical Journal, 2023 Type II radio bursts are often associated with coronal shocks that are typically driven by coronal mass ejections (CMEs) from the Sun. Here we conduct a case study of a type II radio burst that is associated with a C4.5-class flare and a blowout jet, but

Auto Recognition of Solar Radio Bursts Using the C-DCGAN Method
Frontiers in Physics, 2021 Solar radio bursts can be used to study the properties of solar activities and the underlying coronal conditions on the basis of the present understanding of their emission mechanisms. With the construction of observational instruments, around the world,

Frontiers in Astronomy and Space Sciences, 2021 Solar energetic particle (SEP) events are commonly separated in two categories: numerous “impulsive” events of relatively short duration, and a few “gradual” events, where SEP-intensities may stay enhanced over several days at energies up to several tens

Plasma Instability in Front of Ejected Energetic Electrons and Type III Solar Radio Bursts
The Astrophysical JournalType III radio bursts are signatures of the fluxes of near-relativistic electrons ejected during solar flares. These bursts are frequently observed by spacecraft such as the Parker Solar Probe. It has been traditionally believed that these electron beams
