Polarisation of decayless kink oscillations of solar coronal loops. [PDF]

open access: yesNat Commun, 2023
Abstract 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 energy supply. However, unambiguous determination of

Coronal condensations caused by magnetic reconnection between solar coronal loops [PDF]

open access: yesThe Astrophysical Journal Letters, 2018
Employing Solar Dynamics Observatory (SDO)/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.

Unresolved fine-scale structure in solar coronal loop-tops [PDF]

open access: yesThe Astrophysical Journal, 2014
New and advanced space-based observing facilities continue to lower the resolution limit and detect solar coronal loops in greater detail. We continue to discover even finer sub-structures within coronal loop cross sections, in order to understand the ...

Transverse, Propagating Velocity Perturbations in Solar Coronal Loops [PDF]

open access: yesPlasma Physics and Controlled Fusion, 2015
This short review paper gives an overview of recently observed transverse, propagating velocity perturbations in coronal loops. These ubiquitous perturbations are observed to undergo strong damping as they propagate.

Reduced Thermal Conduction in Solar Coronal Loops

open access: yesThe Astrophysical Journal
Thermal conduction plays an important role in the energy balance of the solar coronal plasma. In this paper, we present a new method for deriving observational constraints on the density–temperature relationship for coronal loops from the differential ...

Dynamics of solar coronal loops [PDF]

open access: yesAstronomy & Astrophysics, 2003
We report numerical calculations of the condensation of plasma in short coronal loops, which have several interesting physical consequences. Firstly, we propose a connection between small, cool loops (T < 10 6 K), which constitute one of the basic components of the solar transition region, and prominences, in the sense that the same physical mechanism ...

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.

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.

SIMULATIONS OF SOLAR JETS CONFINED BY CORONAL LOOPS [PDF]

open access: yesThe Astrophysical Journal, 2016
ABSTRACT 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-field regions the jet outflows are confined to the corona.
