Astrophysical Journal, 2013 Solar type I radio storms are long-lived radio emissions from the solar atmosphere. It is believed that these type I storms are produced by energetic electrons trapped within a closed magnetic structure and are characterized by a high ordinary (O) mode polarization. However, the microphysical nature of these emissions is still an open problem. Recently,

Astrophysical Journal, 2013 Low-frequency (80 MHz) imaging and spectral (≈85-20 MHz) observations of moving type IV radio bursts associated with coronal mass ejections (CMEs) from the Sun on three different days are reported. The estimated drift speed of the bursts is in the range ≈150-500 km s–1.

Understanding the Relationship between Solar Coronal Abundances and F10.7 cm Radio Emission [PDF]
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.

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.

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 ...

Imaging spectroscopy reveals spike-like repeating radio burst pairs in the solar corona [PDF]
Nature CommunicationsSolar radio bursts exhibit complex fine structures that reveal intricate coronal plasma dynamics. Here, we report detection of spike-like repeating burst pairs, characterized by two short-lived (0.1-2 s), narrowband components separated by about 4 s at ...
