Understanding the Relationship between Solar Coronal Abundances and F10.7 cm Radio Emission
The Astrophysical Journal, 2023 Sun-as-a-star coronal plasma composition, derived from full-Sun spectra, and the F10.7 radio flux (2.8 GHz) have been shown to be highly correlated ( r = 0.88) during solar cycle 24.

Oscillation of solar radio emission at coronal acoustic cut-off frequency [PDF]
Astronomy & Astrophysics, 2017 Recent SECCHI COR2 observations on board STEREO-A spacecraft have detected density structures at a distance of 2.5--15~R propagating with periodicity of about 90~minutes.

Solar energetic particles and radio burst emission [PDF]
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.

New Results on the Direct Observations of Thermal Radio Emission from a Solar Coronal Mass Ejection [PDF]
Geophysical Research Letters, 2021 AbstractWe report observations of thermal emission from the frontal structure of a coronal mass ejection (CME) using data obtained with the Gauribidanur RAdioheliograPH simultaneously at 80 and 53 MHz on May 1, 2016. The CME was due to activity on the far side of the Sun, but near its limb. No nonthermal radio burst activity was noticed.

CORONAL JETS AS A CAUSE OF MICROWAVE NEGATIVE BURSTS
Solar-Terrestrial Physics, 2020 We have investigated the cause of three “isolated” negative radio bursts recorded one after another at several frequencies in the 1–17 GHz range at the Nobeyama Radio Observatory, Ussuriysk Astrophysical Observatory, and Learmonth Solar Observatory on ...

AN ANALYSIS OF INTERPLANETARY SOLAR RADIO EMISSIONS ASSOCIATED WITH A CORONAL MASS EJECTION [PDF]
The Astrophysical Journal Letters, 2016 ABSTRACT Coronal mass ejections (CMEs) are large-scale eruptions of magnetized plasma that may cause severe geomagnetic storms if Earth directed. Here, we report a rare instance with comprehensive in situ and remote sensing observations of a CME combining white-light, radio, and plasma measurements from four different vantage points. For

The Astrophysical Journal, 2023 Type II solar bursts are radio signatures of shock waves in the solar corona driven by solar flares or coronal mass ejections (CMEs). Therefore, these bursts present complex spectral morphologies in solar dynamic spectra.

Multifrequency Microwave Imaging of Weak Transients from the Quiet Solar Corona
The Astrophysical Journal, 2023 Understanding the dynamics of the quiet solar corona is important for answering key questions including the coronal heating problem. Multiple studies have suggested small-scale magnetic-reconnection events may play a crucial role.

Observations of the coronal dynamics associated with solar radio spike burst emission [PDF]
Astronomy & Astrophysics, 2006 We present the results of an analysis of multi-wavelength data for a solar radio spike burst event which was observed on 1997 November 14 by the Solar Radio Spectrometers of the Astrophysikalisches Institut Potsdam (AIP). Using radio imaging data from the Nancay Radioheliograph we are able to determine the location of the spike burst emission sites in ...
