High-resolution observations of small-scale activity in coronal hole plumes
Astronomy & AstrophysicsContext. Largely radial ray-like structures, termed plumes, are often observed in coronal holes. Plumes have been proposed to channel magnetohydrodynamic (MHD) waves and the solar wind into the heliosphere.

The Pointing Error Due To Laser Propagation in Space Plasma for TianQin Gravitational Wave Detection
Space Weather, Volume 24, Issue 4, April 2026.Abstract TianQin, a space‐borne gravitational wave observatory, is designed to detect gravitational‐wave signals via laser interferometry. As the inhomogeneous space plasma surrounds the inter‐satellite laser links, the propagation of the laser in space plasma can introduce pointing error noise.

On the topology of global coronal magnetic fields [PDF]
, 2014 This thesis considers the magnetic topology of the global solar corona. To understand the magnetic topology we use the magnetic skeleton which provides us with a robust description of the magnetic field.

Current sheets in the solar corona : formation, fragmentation and heating [PDF]
, 2011 In this thesis we investigate current sheets in the solar corona. The well known 1D model for the tearing mode instability is presented, before progressing to 2D where we introduce a non-uniform resistivity.

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 ...

Extreme Ultraviolet Microflashes at Plume Bases: A Candidate for Powering the Corona and Solar Wind?
The Astrophysical JournalSolar plumes—outflows of bright coronal plasma—are a major component of the open-magnetic-field corona and solar wind, but their driving mechanism remains uncertain.

Dynamics of nonlinear resonant slow MHD waves in twisted flux tubes [PDF]
Nonlinear Processes in Geophysics, 2002 Nonlinear resonant magnetohydrodynamic (MHD) waves are studied in weakly dissipative isotropic plasmas in cylindrical geometry. This geometry is suitable and is needed when one intends to study resonant MHD waves in magnetic flux tubes (e.g.

The Astrophysical Journal, 2005 We used three instruments (CDS, EIT, MDI) aboard the Solar and Heliospheric Observatory spacecraft to observe the large sunspot in NOAA Active Region 8539 on 1999 May 9 and 13. The spot contained a bright plume, most easily seen in EUV emission lines formed at 5.2 log T 5.7 (where T is the temperature in K), in its umbra on both dates.

Multi-spacecraft observations of polar coronal plumes
, 2008 Aims.Coronal plumes, along with their structure and rôle in the acceleration of the fast solar wind, are of considerable importance in understanding the physics of the solar atmosphere, in particular, when contrasted with the adjacent plasma, the so ...
