An AB Initio Approach to Solar Coronal Loops [PDF]
The Astrophysical Journal, 2005 Data from recent numerical simulations of the solar corona and transition region are analysed and the magnetic field connection between the low corona and the photosphere is found to be close to that of a potential field. The fieldline to fieldline displacements follow a power law distribution with typical displacements of just a few Mm.

Acoustic response to transverse oscillations in a solar coronal loop [PDF]
Astronomy & Astrophysics, 2021 Context. Magnetohydrodynamic (MHD) waves play an important role in the dynamics and heating of the solar corona. Their investigation also reveals information about the local conditions. Transverse (Alfvénic) oscillations of loops commonly occur in response to solar eruptions. It has been shown that these oscillations elicit an acoustic response through

Comparison of Damping Mechanisms for Transverse Waves in Solar Coronal Loops [PDF]
, 2017 We present a method to assess the plausibility of alternative mechanisms to explain the damping of magnetohydrodynamic transverse waves in solar coronal loops. The considered mechanisms are resonant absorption of kink waves in the Alfvén continuum, phase

EUV FLICKERING OF SOLAR CORONAL LOOPS: A NEW DIAGNOSTIC OF CORONAL HEATING [PDF]
The Astrophysical Journal Letters, 2016 ABSTRACT A previous work of ours found the best agreement between EUV light curves observed in an active region core (with evidence of super-hot plasma) and those predicted from a model with a random combination of many pulse-heated strands with a power-law energy distribution.

Solar Coronal Loops Associated with Small-scale Mixed Polarity Surface Magnetic Fields [PDF]
, 2016 How and where are coronal loops rooted in the solar lower atmosphere? The details of the magnetic environment and its evolution at the footpoints of coronal loops are crucial to understanding the processes of mass and energy supply to the solar corona ...

A Statistical Study of Short-period Decayless Oscillations of Coronal Loops in an Active Region
The Astrophysical Journal, 2023 Coronal loop oscillations are common phenomena in the solar corona, which are often classified as decaying and decayless oscillations. Using the high-resolution observation measured by the Extreme Ultraviolet Imager (EUI) on board the Solar Orbiter, we ...

Plasma injection into a solar coronal loop [PDF]
Astronomy & Astrophysics, 2019 Context. The details of the spectral profiles of extreme UV emission lines from solar active regions contain key information for investigating the structure, dynamics, and energetics of the solar upper atmosphere. Aims. We characterize the line profiles not only through the Doppler shift and intensity of the bulk part of the profile.

Kink Oscillations of Coronal Loops [PDF]
Space Science Reviews, 2021 Kink oscillations of coronal loops, i.e., standing kink waves, is one of the most studied dynamic phenomena in the solar corona. The oscillations are excited by impulsive energy releases, such as low coronal eruptions. Typical periods of the oscillations
