The Highlights of Solar Radio Physics (science nuggets) are short communications written in the language accessible to a non-expert in the specific area. The nugget is a brief description of a new and interesting scientific result, not as detailed as a scientific article, but rather written in a more discursive ‘news & views’ style.

Propagation of Coronal Mass Ejections: Aerodynamic Drag by Nishtha Sachdeva and Prasad Subramanian

by CESRA in Solar Radio Science

Coronal Mass Ejections (CMEs) are hot, massive blobs of plasma and magnetic fields that erupt from the Sun, and are sometimes Earth-directed. Depending on their speed and mass these transients can strongly effect the space weather, causing geomagnetic storms and damage to space bound technologies. It is therefore imperative to [...]...

Diagnostics of the acceleration modulation process based on quasi-periodic variations of flare emission by Kupriyanova et al.*

by CESRA in Solar Radio Science

Quasi-periodic pulsations (QPPs) with the characteristic time scales from a few seconds up to tens of minutes are frequently seen in the time profiles of solar and stellar flare emission (Nakariakov et al., 2016 ). Among all the possibilities of QPPs explanation, two reasons are discussed more actively: magnetohydrodynamic (MHD) [...]... Read more »

An Analysis of Interplanetary Solar Radio Emissions Associated with a Coronal Mass Ejection by V. Krupar et al.*

by CESRA in Solar Radio Science

Type II and type III bursts are generated, via the plasma emission mechanism, when beams of suprathermal electrons interact with the ambient plasma generating radio emissions at the plasma frequency fp (the fundamental emission) or at its second harmonic 2fp (the harmonic emission) [see also previous CESRA highlights here and [...]...

High resolution observations of radio noise storms in the solar corona

by Prasad Subramanian and Claude Mercier in Solar Radio Science

The solar corona is a well known site for particle acceleration – examples range from spectacular large flares to the hard-to-observe nanoflares that are now a leading candidate for coronal heating.... Read more »

On the thermal nature of 140 GHz emission from the 4 July 2012 solar flare by Yuriy Tsap et al.*

by CESRA in Solar Radio Science

The nature of the solar flare sub-THz emission (Kaufmann, 2012) with a positive spectral slope at 200-400 GHz is still not clear..... Read more »

Bright 30 THz impulsive solar bursts by Pierre Kaufmann et al.*

by CESRA in Solar Radio Science

Impulsive 30 THz continuum bursts have been recently observed in solar flares, utilizing small telescopes with a unique and relatively simple optical setup concept (Kaufmann et al. 2015). The most intense burst was observed together with a GOES X2 class event on October 27, 2014, also detected at two sub-THz [...]... Read more »

Particle Acceleration and heating by turbulent reconnection by L. Vlahos, T. Pisokas, H. Isliker, V. Tsiolis and A. Anastasiadis

by CESRA in Solar Radio Science

Fermi (1949) introduced a fundamental stochastic process to solve the problem of particle energization (heating and/or acceleration) in space and astrophysical plasmas. The initial idea of Fermi with randomly moving scatterers (magnetic clouds), was soon replaced with a spectrum of low amplitude (δΒ/Β... Read more »
