On the topology of global coronal magnetic fields
, 2014 This thesis considers the magnetic topology of the global solar corona. To understand the magnetic topology we use the magnetic skeleton which provides us with a robust description of the magnetic field.

Solar Type J Radio Bursts and the Associated Coronal Loop
The Astrophysical JournalThe solar type J radio burst is a variant of type III bursts, which are a probe for understanding solar energetic electrons and local electron density. This study investigates a type J burst event on 2017 September 9.

, 2011 Coronal mass ejections (CMEs) are large-scale explosions on the Sun that expel plasma and magnetic field into the heliosphere. The interplanetary counterparts of CMEs, termed interplanetary CMEs (ICMEs), are often directly observed by spacecraft ...

The nature of moving solar radio bursts associated with coronal mass ejections [PDF]
, 2021 Coronal mass ejections (CMEs) are large-scale eruptions of plasma entrained in a magnetic field. They occur in the solar corona, and from there they propagate into interplanetary space along with the solar wind.

MICROWAVE EMISSION OF SOLAR FLARES: CORONAL MASS EJECTIONS AND SHOCK WAVES
Odessa Astronomical Publications, 2017 Coronal mass ejections (CMEs) mostly affect the geomagnetic field. These structures are observed and studied with coronagraphic images thereforewe don’t see the corona in the plane of the sky and the measurements of the propagation ...

The Efficiency of Harmonic Emissions Excited by Energetic Electrons in Coronal Loops
The Astrophysical JournalMagnetic reconnection is a key process that drives the energy release in solar flares. This process can occur at multiple locations along the coronal loop.

Emission Characteristics of Energetic Electrons with Crescent-shaped Velocity Distributions
The Astrophysical JournalSolar flares release magnetic energy through reconnection, accelerating electrons into nonthermal velocity distributions, including crescent-shaped electron populations. These energetic electron distributions are crucial in driving instabilities that can

Radio Signature of the Strong Compression between a Streamer and a Coronal Hole Boundary
The Astrophysical Journal LettersWe present evidence of the first detection of the radio signature at metric wavelengths of the strong compression between a helmet streamer (HS) and the boundary of a coronal hole (CH) using radio observations from the Callisto MEXICO-LANCE and ALASKA ...

The investigation of quasi-separatrix layers in solar magnetic fields
, 2011 The structure of the magnetic field is often an important factor in many energetic processes in the solar corona. To determine the topology of the magnetic field features such as null points, separatrix surfaces, and separators must be found.
