Antenna Performance Analysis for Decameter Solar Radio Observations

, 2011
Decameter wavelength radio emission is finely structured in solar bursts. For their research it is very important to use a sufficient sensitivity of antenna systems.

Quantifying Weak Nonthermal Solar Radio Emission at Low Radio Frequencies [PDF]

The Astrophysical Journal, 2018
Abstract The recent availability of fine-grained high-sensitivity data from the new generation of low radio frequency instruments such as the Murchison Widefield Array (MWA) has opened up opportunities for using novel techniques for characterizing the nature of solar emission at these frequencies. Here we use this opportunity to look for

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,

Survey on solar X-ray flares and associated coherent radio emissions

, 2004
The radio emission during 201 X-ray selected solar flares was surveyed from 100 MHz to 4 GHz with the Phoenix-2 spectrometer of ETH Zurich. The selection includes all RHESSI flares larger than C5.0 jointly observed from launch until June 30, 2003 ...

Radio Emissions from Solar Active Regions [PDF]

Space Science Reviews, 2007
Solar active region coronae are known for strong magnetic fields permeating tenuous plasma, which makes them an ideal astronomical laboratory for magnetohydrodynamics research. It is, however, relatively less known that this physical condition also permits a very efficient radiation mechanism, gyro-resonant emission, produced by hot electrons gyrating ...

Detection of Radio Emission from Superflaring Solar-type Stars in the VLA Sky Survey

The Astrophysical Journal
Solar-type stars have been observed to flare at optical wavelengths with energies much higher than is observed for the Sun. To date, no counterparts have been observed at longer wavelengths.

Radio Spectral Evolution of an X-ray Poor Impulsive Solar Flare: Implications for Plasma Heating and Electron Acceleration

, 2007
We present radio and X-ray observations of an impulsive solar flare that was moderately intense in microwaves, yet showed very meager EUV and X-ray emission.
