Topological structure of the magnetic solar corona [PDF]

, 2007
The solar corona is a highly complex and active plasma environment, containing many exotic phenomena such as solar flares, coronal mass ejections, prominences, coronal loops, and bright points.

Determining the Polarization of a Coronal Standing Kink Oscillation Using Spectral Imaging Techniques with CoMP

The Astrophysical Journal
Coronal oscillations offer insight into energy transport and driving in the solar atmosphere. Knowing its polarization state helps constrain a wave’s displacement and velocity amplitude, improving estimates of wave energy flux and deposition rate.

Unprecedented 19 Day Type IV Radio Burst as a Corotating Electron Reservoir

The Astrophysical Journal Letters
We report a hectometric (0.5–3 MHz) type IV continuum observed over nearly 19 days (2025 August 21–September 9) in three successive visibility windows as the source corotates with the Sun—first at Solar Orbiter, then 12 days later in the near-Earth ...

Three-dimensional kink modes in solar coronal slabs: Group velocities and their implications for impulsively excited waves

Astronomy & Astrophysics
Context. Little attention has been paid to group velocities of three-dimensional (3D) magnetohydrodynamic (MHD) waves in solar coronal seismology. Aims.

Coronal seismology using transverse loop oscillations [PDF]

, 2009
Coronal seismology exploits the properties of magnetohydrodynamics in the corona of the Sun to diagnose the local plasma. Therefore, seismology complements direct diagnostic techniques, which suffer from line-of-sight integration or may not give access ...

Electron transport in a radiation-dominated plasma

Astronomy & Astrophysics
Context. Bremsstrahlung scattering of fast electrons on ions can be enhanced by the microwave radiation present in the solar corona. It can account for the electron diffusive transport along magnetic loops and high precipitation rates.
