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.

Large-scale Globally Propagating Coronal Waves
Living Reviews in Solar Physics, 2015 Large-scale, globally propagating wave-like disturbances have been observed in the solar chromosphere and by inference in the corona since the 1960s. However, detailed analysis of these phenomena has only been conducted since the late 1990s.

Coronal Waves and Oscillations
Living Reviews in Solar Physics, 2005 Wave and oscillatory activity of the solar corona is confidently observed with modern imaging and spectral instruments in the visible light, EUV, X-ray and radio bands, and interpreted in terms of magnetohydrodynamic (MHD) wave theory.

Solar Stereoscopy and Tomography
Living Reviews in Solar Physics, 2011 We review stereoscopic and tomographic methods used in the solar corona, including ground-based and space-based measurements, using solar rotation or multiple spacecraft vantage points, in particular from the STEREO mission during 2007--2010 ...

Recent advances in solar coronal extreme ultraviolet waves
Proceedings of the Royal Society A: Mathematical, Physical and Engineering SciencesSolar coronal extreme ultraviolet (EUV) waves are spectacular propagating disturbances in the appearance of EUV emission enhancements in the solar corona, similar to the tsunamis on the Earth. These ‘solar tsunamis’ are closely associated with various solar eruptions, from large-scale coronal mass ejections (CMEs) and solar flares to small-scale solar ...

Reviews of Modern Plasma PhysicsAbstractMacroscopic wave and oscillatory phenomena ubiquitously detected in the plasma of the corona of the Sun are interpreted in terms of magnetohydrodynamic theory. Fast and slow magnetoacoustic waves are clearly distinguished in observations. Properties of coronal magnetohydrodynamic waves are determined by local parameters of the plasma, including

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 ...
