Large-scale Bright Fronts in the Solar Corona: A Review of "EIT waves"

open access: yes, 2010
``EIT waves" are large-scale coronal bright fronts (CBFs) that were first observed in 195 \AA\ images obtained using the Extreme-ultraviolet Imaging Telescope (EIT) onboard the \emph{Solar and Heliospheric Observatory (SOHO)}. Commonly called ``EIT waves"

Propagating transverse waves in soft X-ray coronal jets [PDF]

open access: yes, 2009
Aims. The theoretical model for magnetohydrodynamic (MHD) modes guided by a field-aligned plasma cylinder with a steady flow is adapted to interpret transverse waves observed in solar coronal hot jets, discovered with Hinode/XRT in terms of fast ...

Three-dimensional propagation of kink wave trains in solar coronal slabs

open access: yesMonthly Notices of the Royal Astronomical Society: Letters, 2022
ABSTRACT Impulsively excited wave trains are of considerable interest in solar coronal seismology. To our knowledge, however, it remains to examine the three-dimensional (3D) dispersive propagation of impulsive kink waves in straight, field-aligned, symmetric, low-beta, slab equilibria that are structured only in one transverse direction.

On the Freeze‐In Distance of Solar Wind Fluid Entropy Variability in the Corona

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The strong correlation between solar wind entropy and the frozen‐in ion charge state ratio O7+/O6+ ${\mathrm{O}}^{7+}/{\mathrm{O}}^{6+}$ indicates that entropy variability on timescales of hours or longer is preserved from its solar source. This prompts the question: where in the solar atmosphere does this entropy variability come from, and at

On the Existence of Long-period Decayless Oscillations in Short Active Region Loops

open access: yesThe Astrophysical Journal
Decayless kink oscillations, characterized by their lack of decay in amplitude, have been detected in coronal loops of varying scales in active regions, the quiet Sun, and coronal holes. Short-period (

Compression of Mercury's Dayside Magnetopause to the Surface: A Three‐Dimensional Model of Magnetospheric Structure and Dynamics

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We apply a hybrid model (kinetic ions, fluid electrons) to provide context for MErcury Surface Space ENvironment, GEochemistry, and Ranging (MESSENGER) observations of Disappearing Dayside Magnetosphere (DDM) events at Mercury. Such events have been observed on four occasions and are caused by Coronal Mass Ejections completely removing the ...

Impulsively Excited Quasiperiodic Fast-propagating Waves in the Solar Corona

open access: yesThe Astrophysical Journal
Quasiperiodic fast-propagating (QFP) waves excited by an impulsive, spatially localized velocity perturbation in a curved coronal loop are investigated with three-dimensional numerical simulations.

Secondary Waves, and/or the "Reflection" From and "Transmission" Through a Coronal Hole of an EUV Wave Associated With the 2011 February 15 X2.2 Flare Observed With SDO/AIA and STEREO/EUVI

open access: yes, 2012
For the first time, the kinematic evolution of a coronal wave over the entire solar surface is studied. Full Sun maps can be made by combining images from the Solar Terrestrial Relations Observatory satellites, Ahead and Behind, and the Solar Dynamics ...

STUDY OF SOLAR ENERGETIC PARTICLE ASSOCIATIONS WITH CORONAL EXTREME-ULTRAVIOLET WAVES [PDF]

open access: yesThe Astrophysical Journal, 2015
We study the relationship between large gradual solar energetic particle (SEP) events and associated extreme-ultraviolet (EUV) wave properties in 16 events that occurred between 2010 August and 2013 May and were observed by SDO, the Solar and Heliospheric Observatory (SOHO), and/or STEREO.
