The Astrophysical Journal, 2023 Type II solar bursts are radio signatures of shock waves in the solar corona driven by solar flares or coronal mass ejections (CMEs). Therefore, these bursts present complex spectral morphologies in solar dynamic spectra.

Observations of the coronal dynamics associated with solar radio spike burst emission [PDF]
Astronomy & Astrophysics, 2006 We present the results of an analysis of multi-wavelength data for a solar radio spike burst event which was observed on 1997 November 14 by the Solar Radio Spectrometers of the Astrophysikalisches Institut Potsdam (AIP). Using radio imaging data from the Nancay Radioheliograph we are able to determine the location of the spike burst emission sites in ...

Multifrequency Microwave Imaging of Weak Transients from the Quiet Solar Corona
The Astrophysical Journal, 2023 Understanding the dynamics of the quiet solar corona is important for answering key questions including the coronal heating problem. Multiple studies have suggested small-scale magnetic-reconnection events may play a crucial role.

Solar Radio Bursts Associated with In Situ Detected Energetic Electrons in Solar Cycles 23 and 24
Universe, 2022 The first comprehensive analysis between the in situ detected solar energetic electrons (SEEs) from ACE/EPAM satellite and remotely observed radio signatures in solar cycles (SCs) 23 and 24 (1997–2019) is presented.

Coronal Mass Ejections and Solar Radio Emissions (invited) [PDF]
PLANETARY RADIO EMISSIONS VII, 2011 Three types of low-frequency nonthermal radio bursts are associated with coronal mass ejections (CMEs): Type III bursts due to accelerated electrons propagating along open magnetic field lines, type II bursts due to electrons accelerated in shocks, and type IV bursts due to electrons trapped in post-eruption arcades behind CMEs.

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 Astrophysical Journal, 2022 Abstract We simulate possible stellar coronal mass ejection (CME) scenarios over the magnetic cycle of ϵ Eridani (18 Eridani; HD 22049). We use three separate epochs from 2008, 2011, and 2013, and estimate the radio emission frequencies associated with these events.
