Weak Solar Radio Bursts from the Solar Wind Acceleration Region Observed by the Parker Solar Probe and Its Probable Emission Mechanism

open access: yesThe Astrophysical Journal
The Parker Solar Probe (PSP) provides us with an unprecedentedly close approach to the observation of the Sun and hence the possibility of directly understanding the elementary process that occurs on the kinetic scale of particles' collective interaction

First Detection of Low-frequency Striae in Interplanetary Type III Radio Bursts

open access: yesThe Astrophysical Journal Letters
We report the first detection of type III solar radio burst striae in the 30–80 kHz range, observed by the Cluster-4 spacecraft during an exceptionally quiet solar period.

Solar influences in the heliosphere: understanding coronal mass ejections and their associated magnetic clouds [PDF]

open access: yes, 2011
Coronal mass ejections (CMEs) are large-scale explosions on the Sun that expel plasma and magnetic field into the heliosphere. The interplanetary counterparts of CMEs, termed interplanetary CMEs (ICMEs), are often directly observed by spacecraft ...

Fine Structures of Narrowband Type III Bursts in a Solar Flare

open access: yesThe Astrophysical Journal
In this paper, we investigate the fine structures of a group of narrowband type III radio bursts on the decay phase of an M3.1 solar flare on 2025 February 3.

Improving Solar Extreme Ultraviolet Irradiance Modeling with Differential Emission Measure Informed Spectra

open access: yesThe Astrophysical Journal
Solar extreme ultraviolet (EUV) irradiance predominantly originates from the chromosphere and corona, and variations in EUV irradiance are a significant driver of space weather at Earth, causing increased satellite drag, radio communication disruptions ...

An evaluation of potential solar radio emission power threat on GPS and GLONASS performance

open access: yes, 2012
The L-band solar radio emission has recently been regarded as a potential threat to stable GPS and GLONASS performance. However, the threat has not been completely investigated or assessed so far.

ABSTRACT RADIO MEASUREMENTS OF CORONAL MAGNETIC FIELDS

open access: yes, 2008
The measurement of magnetic field strengths in the solar corona using radio observations is reviewed. This is a well established technique that exploits the fact that the electron gyrofrequency for typical coronal magnetic field strengths (100–2000 Gauss)

New Insights into Type-I Solar Noise Storms from High Angular Resolution Spectroscopic Imaging with the Upgraded Giant Metrewave Radio Telescope

open access: yesThe Astrophysical Journal
Type-I solar noise storms are perhaps the most commonly observed active radio emissions from the Sun at meter-wavelengths. Noise storms have a long-lived and wideband continuum background with superposed islands of much brighter narrowband and short ...

Radio Emission of Flares and Coronal Mass Ejections Invited Review

open access: yes, 2008
We review recent progress on our understanding of radio emission from solar flares and coronal mass ejections (CMEs) with emphasis on those aspects of the subject that help us address questions about energy release and its properties, the configuration ...
