Anisotropic Radio-Wave Scattering and the Interpretation of Solar Radio Emission Observations [PDF]

The Astrophysical Journal, 2019
The observed properties (i.e., source size, source position, time duration, decay time) of solar radio emission produced through plasma processes near the local plasma frequency, and hence the interpretation of solar radio bursts, are strongly influenced

Solar radio emission as a disturbance of radiomobile networks. [PDF]

Sci Rep, 2022
AbstractThis paper analyses the effects of solar radio emissions in the radiomobile context, for the first time leveraging massive European Telecommunications Standards Institute (ETSI) 3rd Generation Partnership Program (3GPP) Minimization of Drive Test (MDT) radio measures produced by 4G LTE (Long Term Evolution) terminals and by 4G LTE Base Station ...

Radio emission from acceleration sites of solar flares [PDF]

The Astrophysical Journal, 2009
This Letter takes up the question of what radio emission is produced by electrons at the very acceleration site of a solar flare. Specifically, we calculate incoherent radio emission produced within two competing acceleration models - stochastic ...

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

Frontiers 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 ...

Solar Radio Emissions and Ultralight Dark Matter

Universe, 2023
Ultralight axions and dark photons are well-motivated dark matter candidates. Inside the plasma, once the mass of ultralight dark matter candidates equals the plasma frequency, they can resonantly convert into electromagnetic waves, due to the coupling between the ultralight dark matter particles and the standard model photons.

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

The 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.

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

, 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 ...

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

Radio 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.

The Solar Wind in Time II: 3D stellar wind structure and radio emission [PDF]

, 2019
International audienceIn this work, we simulate the evolution of the solar wind along its main-sequence lifetime andcompute its thermal radio emission. To study the evolution of the solar wind, we use a sample ofsolar mass stars at different ages.
