Polarisation of decayless kink oscillations of solar coronal loops. [PDF]
Nat Commun, 2023 Decayless kink oscillations of plasma loops in the solar corona may contain an answer to the enigmatic problem of solar and stellar coronal heating. The polarisation of the oscillations gives us a unique information about their excitation mechanisms and ...

Coronal Condensations Caused by Magnetic Reconnection between Solar Coronal Loops [PDF]
The Astrophysical Journal Letters, 2018 Employing Solar Dynamics Observatory/Atmospheric Imaging Assembly (AIA) multi-wavelength images, we report the coronal condensation during the magnetic reconnection (MR) between a system of open and closed coronal loops.

Standing Kink Waves in Sigmoid Solar Coronal Loops: Implications for Coronal Seismology [PDF]
The Astrophysical Journal Letters, 2020 Using full three-dimensional magnetohydrodynamic numerical simulations, we study the effects of magnetic field sigmoidity or helicity on the properties of the fundamental kink oscillation of solar coronal loops.

The Heating of Solar Coronal Loops by Alfvén Wave Turbulence [PDF]
The Astrophysical Journal, 2017 In this paper we further develop a model for the heating of coronal loops by Alfvén wave turbulence (AWT). The Alfvén waves are assumed to be launched from a collection of kilogauss flux tubes in the photosphere at the two ends of the loop. Using a three-

Measurements of Coronal Magnetic Field Strengths in Solar Active Region Loops [PDF]
Astrophysical Journal Letters, 2021 The characteristic electron densities, temperatures, and thermal distributions of 1 MK active region loops are now fairly well established, but their coronal magnetic field strengths remain undetermined.

Slow-Mode Magnetoacoustic Waves in Coronal Loops [PDF]
Space Science Reviews, 2021 Rapidly decaying long-period oscillations often occur in hot coronal loops of active regions associated with small (or micro-) flares. This kind of wave activity was first discovered with the SOHO/SUMER spectrometer from Doppler velocity measurements of ...

Transverse, propagating velocity perturbations in solar coronal loops [PDF]
Plasma Physics and Controlled Fusion, 2015 As waves and oscillations carry both energy and information, they have enormous potential as a plasma heating mechanism and, through seismology, to provide estimates of local plasma properties which are hard to obtain from direct measurements.

Magnetic reconnection between a solar filament and nearby coronal loops [PDF]
Nature Physics, 2016 Observing magnetic reconnection directly is generally difficult, but looking at the reconnection between erupting solar filaments and nearby coronal loops uncovers many fine details with unprecedented clarity.

SIMULATIONS OF SOLAR JETS CONFINED BY CORONAL LOOPS [PDF]
The Astrophysical Journal, 2015 Coronal jets are collimated, dynamic events that occur over a broad range of spatial scales in the solar corona. In the open magnetic field of coronal holes, jets form quasi-radial spires that can extend far out into the heliosphere, while in closed ...
