Sawtooth oscillations in solar flare radio emission [PDF]

Astronomy & Astrophysics, 2001
For the first time, we found a spectral fine structure of solar meter wave radio burst emission which can be due to sawtooth oscillations in the hot flare plasma. This finding newly underlines an analogy between coronal and laboratory plasma processes. The sawteeth occur during the impulsive flare phase hard X-ray emission and consist of a sequence of ...

Performance of radio-based detection for operational monitoring of M5+ class solar flares

Journal of Space Weather and Space Climate
Early detection of major solar flares is critical due to their potential to disturb radar and radio systems. Typically, soft X-ray flux is used to monitor and classify solar flares, but since this flux has to be measured in space, it means that its ...

Development of a local empirical model of ionospheric total electron content (TEC) and its application for studying solar-ionospheric effects

Scientific Reports, 2021
Regular and irregular variations in total electron content (TEC) are one of the most significant observables in ionospheric studies. During the solar cycle 24, the variability of ionosphere is studied using global positioning system derived TEC at a mid ...

Radio Behavior of Solar Post-Flare Loops [PDF]

Proceedings of the International Astronomical Union, 2006
The spectral and source characteristics of a complex radio burst observed with the spectrometers of China and the Nobeyama Radio Heliograph are analyzed. This burst presents two separate burst peaks occurred in different frequency range (broad-band microwave and narrow-band decimeter wavelengths). We stress that the late phase radio bursts in decimeter

Embedded Interactions and Selective Disclosure: Network Effects on Conversations aboard Skylab

Symbolic Interaction, Volume 49, Issue 4, Page 1031-1056, November 2026.
How do absent others influence our interactions? We argue in this paper that interactions are embedded within networks formed by chains of specific relationships between known third parties. The anticipation of future interactions with external others conditions our interpretation of the current situation and affects our behavior in the interaction. We

Energy and spectral analysis of confined solar flares from radio and X-ray observations

, 2021
International audienceThe energy and spectral shape of radio bursts may help us understand the generation mechanism of solar eruptions, including solar flares, coronal mass ejections, eruptive filaments, and various scales of jets. The different kinds of

Radio Observations of High Energy Solar Flares [PDF]

Highlights of Astronomy, 2002
AbstractIn this paper we discuss some recent observations of radio emission produced by high energy electrons resulting from solar flares. We discuss the spatial structure of simple weak spiky burst emissions observed simultaneously, at 17 and 34 GHz with the Nobeyama Radio Heliograph (NoRH).

The Spatial Localization of Storm‐Time ULF Waves Due To Plasmaspheric Plumes

Journal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract The generation and propagation of Ultra Low Frequency (ULF) waves are intrinsically coupled to the cold plasma population in the terrestrial magnetosphere. During geomagnetic storms, extreme reconfigurations of the cold plasma create a complex and dynamic system that drastically modifies this coupling.

Comparison between GOES flares, SOHO/LASCO CMEs and RSTN 1.4 GHz solar radio bursts

, 2020
Study 1.4 GHz solar radio bursts as counterparts to coronal mass ejections. For a list of GOES X-ray flares of class M5 or higher, this dataset provides the time integral of their associated 1.4 GHz solar radio burst and compares them with the speed ...

Type III radio bursts associated with jets in two solar flares

Astronomy & Astrophysics
Context. A challenging issue is the significant velocity discrepancy between jets and energetic electrons accelerated by magnetic reconnection in solar flares. Aims.
