Ion-cyclotron waves in solar coronal hole [PDF]
New Astronomy, 2012 We investigate the effect of the Plume/Interplume Lane (PIPL) structure of the solar Polar Coronal Hole (PCH) on the propagation characteristics of ion-cyclotron waves (ICW). The gradients of physical parameters determined by SOHO and TRACE satellites both parallel and perpendicular to the magnetic field are considered with the aim of determining how ...

ALFVÉN WAVE SOLAR MODEL (AWSoM): CORONAL HEATING [PDF]
The Astrophysical Journal, 2014 We present a new version of the Alfven Wave Solar Model (AWSoM), a global model from the upper chromosphere to the corona and the heliosphere. The coronal heating and solar wind acceleration are addressed with low-frequency Alfven wave turbulence. The injection of Alfven wave energy at the inner boundary is such that the Poynting flux is proportional ...

Coronal Transverse Magnetohydrodynamic Waves in a Solar Prominence [PDF]
Science, 2007 Solar prominences are cool 10 4 kelvin plasma clouds supported in the surrounding 10 6 kelvin coronal plasma by as-yet-undetermined mechanisms. Observations from Hinode show fine-scale threadlike structures oscillating in the plane of the sky with periods of several minutes.

Standing Kink Waves in Sigmoid Solar Coronal Loops: Implications for Coronal Seismology [PDF]
The Astrophysical Journal Letters, 2020 Abstract Using full three-dimensional magnetohydrodynamic numerical simulations, we study the effects of magnetic field sigmoidity or helicity on the properties of the fundamental kink oscillation of solar coronal loops. Our model consists of a single denser coronal loop, embedded in a plasma with dipolar force-free magnetic field with a

Impulsively generated kink wave trains in solar coronal slabs
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT We numerically follow the response of density-enhanced slabs to impulsive, localized, transverse velocity perturbations by working in the framework of ideal magnetohydrodynamics (MHD). Both linear and non-linear regimes are addressed. Kink wave trains are seen to develop along the examined slabs, sharing the characteristics that

Impulsive Solar Energetic Particle Events: Extreme-Ultraviolet Waves and Jets
Frontiers in Astronomy and Space Sciences, 2022 Impulsive solar energetic particle (ISEP) events show peculiar elemental composition, with enhanced 3He and heavy-ion abundances, markedly different from our Solar System composition.

A Statistical Analysis of the Solar Phenomena Associated with Global EUV Waves [PDF]
, 2017 Solar eruptions are the most spectacular events in our solar system and are associated with many different signatures of energy release including solar flares, coronal mass ejections, global waves, radio emission and accelerated particles. Here, we apply

Observational Quantification of the Energy Dissipated by Alfv\'en Waves in a Polar Coronal Hole: Evidence that Waves Drive the Fast Solar Wind [PDF]
, 2013 We present a measurement of the energy carried and dissipated by Alfv\'en waves in a polar coronal hole. Alfv\'en waves have been proposed as the energy source that heats the corona and drives the solar wind.
