Waves in Solar Coronal Loops [PDF]
Geophysical Monograph Series, 2016 Recent observations have revealed the ubiquitous presence of magnetohydrodynamic (MHD) waves and oscillations in the solar corona. The aim of this review is to present recent progress in the observational study of four types of wave (or oscillation ...

STATISTICAL EVIDENCE FOR THE EXISTENCE OF ALFVÉNIC TURBULENCE IN SOLAR CORONAL LOOPS [PDF]
The Astrophysical Journal, 2014 Recent observations have demonstrated that waves capable of carrying large amounts of energy are ubiquitous throughout the solar corona. However, the question of how this wave energy is dissipated (on which timescales and length scales) and released into

Self-organized braiding in solar coronal loops [PDF]
Journal of Plasma Physics, 2015 In this paper, we investigate the evolution of braided solar coronal loops. We assume that coronal loops consist of several internal strands which twist and braid about each other. Reconnection between the strands leads to small flares and heating of the

EVIDENCE FOR EVAPORATION-INCOMPLETE CONDENSATION CYCLES IN WARM SOLAR CORONAL LOOPS [PDF]
Astrophysical Journal, 2015 Quasi-constant heating at the footpoints of loops leads to evaporation and condensation cycles of the plasma: thermal non-equilibrium (TNE). This phenomenon is believed to play a role in the formation of prominences and coronal rain. However, it is often

Coronal Loops: Observations and Modeling of Confined Plasma
Living Reviews in Solar Physics, 2014 Coronal loops are the building blocks of the X-ray bright solar corona. They owe their brightness to the dense confined plasma, and this review focuses on loops mostly as structures confining plasma.

SOLAR CORONAL LOOPS RESOLVED BY HINODE AND THE SOLAR DYNAMICS OBSERVATORY [PDF]
Astrophysical Journal Letters, 2012 Despite decades of studying the Sun, the coronal heating problem remains unsolved. One fundamental issue is that we do not know the spatial scale of the coronal heating mechanism.

Flare-induced decay-less transverse oscillations in solar coronal loops [PDF]
Astronomy & Astrophysics, 2021 Evidence of flare induced, large-amplitude, decay-less transverse oscillations is presented. A system of multi-thermal coronal loops as observed with the Atmospheric Imaging Assembly (AIA), exhibit decay-less transverse oscillations after a flare erupts ...

Kink Oscillations in Solar Coronal Loops with Elliptical Cross Sections. I. The Linear Regime [PDF]
Astrophysical Journal, 2020 The cross sections of solar coronal loops are suggested to be rarely circular. We examine linear kink oscillations in straight, density-enhanced, magnetic cylinders with elliptical cross sections by solving the three-dimensional magnetohydrodynamic ...

Dynamics of solar coronal loops [PDF]
Astronomy & Astrophysics, 2003 Observations in X-ray and EUV of the solar corona reveal the existence of very complex and dynamic structures made of plasma magnetically confined in loops. These structures can be studied by means of one-dimensional hydrodynamical loop models. Here we use a Lagrangian-remap code to simulate the dynamics of solar coronal loops with the purpose of ...
