Coronal Loops: Observations and Modeling of Confined Plasma [PDF]

open access: yesLiving 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.

Coronal Loop Detection Using Multiscale Convolutional Neural Networks

open access: yesThe Astrophysical Journal Supplement Series, 2023
Solar magnetic fields play an important role in many solar activities, such as the solar wind, coronal mass ejections, and coronal oscillation. Coronal loops are curvilinear structures in the solar atmosphere and are closely related to coronal magnetic ...

High-order Harmonics of a Kink Wave and a Narrow Quasiperiodic Fast-propagating Wave Train Excited Simultaneously in a Plasma Resonator

open access: yesThe Astrophysical Journal, 2023
We present the observations of multimode kink waves and a narrow quasiperiodic fast-propagating (QFP) wave train in association with a jet on 2011 December 11.

Coronal Loops with Different Metallicities and Generalized RTV Scaling Laws

open access: yesThe Astrophysical Journal, 2023
Stellar metallicity is a critical factor to characterize the stellar coronae because it directly affects the radiative energy loss from the atmosphere.

Oscillation and Evolution of Coronal Loops in a Dynamical Solar Corona

open access: yesFrontiers in Astronomy and Space Sciences, 2020
Observations have revealed two regimes of kink oscillations of coronal loops. Large amplitude oscillations excited by impulsive energy releases such as coronal mass ejections are characterized by their strong damping by resonant absorption.

The redshifted footpoints of coronal loops [PDF]

open access: yesAnnales Geophysicae, 2008
The physics of coronal loops holds the key to understanding coronal heating and the flow of mass and energy in the region. However, the energy source, structure maintenance and mass balance in coronal loops are not yet fully understood.

Solar stereoscopy – where are we and what developments do we require to progress? [PDF]

open access: yesAnnales Geophysicae, 2009
Observations from the two STEREO-spacecraft give us for the first time the possibility to use stereoscopic methods to reconstruct the 3-D solar corona. Classical stereoscopy works best for solid objects with clear edges.

A Possible Mechanism for the “Late Phase” in Stellar White-light Flares

open access: yesThe Astrophysical Journal, 2023
M dwarf flares observed by the Transiting Exoplanet Survey Satellite (TESS) sometimes exhibit a peak-bump light-curve morphology, characterized by a secondary, gradual peak well after the main, impulsive peak.

A Statistical Study of Short-period Decayless Oscillations of Coronal Loops in an Active Region

open access: yesThe 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 ...
