Relationship between solar wind corotating interaction regions and the phasing and intensity of Saturn kilometric radiation bursts [PDF]

open access: yes, 2008
Voyager spacecraft measurements of Saturn kilometric radiation (SKR) identified two features of these radio emissions: that they pulse at a period close to the planetary rotation period, and that the emitted intensity is correlated with the solar wind ...

On the association of solar radio emission and solar prominences. [PDF]

open access: yesThe Astronomical Journal, 1956
Prominence cinematograms made at Sacramento Peak and climax in the years 1949?55 have been examined and compared with the solar radio records at 167 Mc/s. No close connexion was found between limb events and radio events, but some eruptions were found to be associated with simultaneous radio bursts. Three such cases are discussed in detail.

An Anisotropic Density Turbulence Model from the Sun to 1 au Derived from Radio Observations

open access: yesThe Astrophysical Journal, 2023
Solar radio bursts are strongly affected by radio-wave scattering on density inhomogeneities, changing their observed time characteristics, sizes, and positions.

CORONAL JETS AS A CAUSE OF MICROWAVE NEGATIVE BURSTS

open access: yesSolar-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 ...

Radio Measurements of the Magnetic Field in the Solar Chromosphere and the Corona

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The structure of the upper solar atmosphere, on all observable scales, is intimately governed by the magnetic field. The same holds for a variety of solar phenomena that constitute solar activity, from tiny transient brightening to huge Coronal Mass ...

Millimeter and X-Ray Emission from the 5 July 2012 Solar Flare [PDF]

open access: yes, 2022
The 5 July 2012 solar flare SOL2012-07-05T11:44 (11:39 – 11:49 UT) with an increasing millimeter spectrum between 93 and 140 GHz is considered. We use space and ground-based observations in X-ray, extreme ultraviolet, microwave, and millimeter wave ...

THE ROLE OF RADIO WAVE PROPAGATION EFFECTS IN THE SOLAR CORONA TO INTERPRET THE BEHIND-LIMB BURSTS

open access: yesRadio Physics and Radio Astronomy, 2016
Purpose: The radio emission propagation of solar radio bursts in the solar corona which sources are located on the far side of the Sun relative to the observer on Earth is studied.

On the mechanisms of sporadic solar radio emission [PDF]

open access: yesSymposium - International Astronomical Union, 1959
The mechanism that generates sporadic (nonthermal) solar radio emission, which is of great interest to radio astronomy and solar physics, is rather obscure. Recently the authors considered this problem [1, 2, 3] and this report gives their summary.
