Continuous upflows and sporadic downflows observed in active regions
, 2011 We present a study of the temporal evolution of coronal loops in active regions and its implications for the dynamics in coronal loops. We analyzed images of the Atmospheric Imaging Assembly (AIA) on the Solar Dynamics Observatory (SDO) at multiple ...

, 1980 In the past few years it has been realised that loop structures are an important feature of the solar corona, Presumably, these structures outline the local magnetic field and in this thesis some theoretical aspects of solar coronal loops are considered.

Impulsively Excited Quasiperiodic Fast-propagating Waves in the Solar Corona
The Astrophysical JournalQuasiperiodic fast-propagating (QFP) waves excited by an impulsive, spatially localized velocity perturbation in a curved coronal loop are investigated with three-dimensional numerical simulations.

Understanding the Duration of Solar and Stellar Flares at Various Wavelengths
The Astrophysical Journal, 2023 Recent irradiance measurements from numerous heliophysics and astrophysics missions including Solar Dynamics Observatory (SDO), GOES, Kepler, TESS, Chandra, the X-ray Multi-Mirror Mission, and NICER have provided critical input into understanding the ...

Magneto-seismology of solar atmospheric loops by means of longitudinal oscillations
, 2012 There is increasingly strong observational evidence that slow magnetoacoustic modes arise in the solar atmosphere. Solar magneto-seismology is a novel tool to derive otherwise directly un-measurable properties of the solar atmosphere when ...

Motion magnification in coronal seismology [PDF]
, 2016 We introduce a new method for the investigation of low-amplitude transverse oscillations of solar plasma non-uniformities, such as coronal loops, individual strands in coronal arcades, jets, prominence fibrils, polar plumes, and other contrast features ...

Recent Applications of Bayesian Methods to the Solar Corona
Frontiers in Astronomy and Space Sciences, 2022 Solar coronal seismology is based on the remote diagnostics of physical conditions in the corona of the Sun by comparison between model predictions and observations of magnetohydrodynamic wave activity.

Particle acceleration and transport in reconnecting twisted loops in a stratified atmosphere
, 2014 Twisted coronal loops should be ubiquitous in the solar corona. Twisted magnetic fields contain excess magnetic energy, which can be released during magnetic reconnection, causing solar flares. The aim of this work is to investigate magnetic reconnection,

Solar Flares as Cascades of Reconnecting Magnetic Loops
, 2003 A model for the solar coronal magnetic field is proposed where multiple directed loops evolve in space and time. Loops injected at small scales are anchored by footpoints of opposite polarity moving randomly on a surface.
