CDS wide slit time-series of EUV coronal bright points [PDF]

, 2004
Wide slit (90" x 240" ) movies of four Extreme Ultraviolet coronal bright points (BPs) obtained with the Coronal Diagnostic Spectrometer (CDS) on board the Solar and Heliospheric Observatory (SoHO) have been inspected.

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 ...

Broad and Bidirectional Narrow Quasiperiodic Fast-propagating Wave Trains Associated with a Filament-driven Halo Coronal Mass Ejection on 2023 April 21

The Astrophysical Journal
This paper presents three distinct wave trains that occurred on 2023 April 21: a broad quasiperiodic fast-propagating (QFP) wave train and bidirectional narrow QFP wave trains.

The propagation and damping of slow magnetoacoustic waves in the solar atmosphere

, 2012
The propagation and damping of slow magnetoacoustic waves in the solar atmosphere is investigated, with particular emphasis placed on waves with periodicities of five minutes. The basic model of a uniform temperature loop is extended by the addition of

Dynamical age of solar wind turbulence in the outer heliosphere

, 1998
In an evolving turbulent medium, a natural timescale can be defined in terms of the energy decay time. The time evolution may be complicated by other effects such as energy supply due to driving, and spatial inhomogeneity.

The driving mechanisms of particle precipitation during the moderate geomagnetic storm of 7 January 2005 [PDF]

, 2007
International audienceThe arrival of an interplanetary coronal mass ejection (ICME) triggered a sudden storm commencement (SSC) at ~09:22 UT on the 7 January 2005. The ICME followed a quiet period in the solar wind and interplanetary magnetic field (IMF).

Magnetohydrodynamic Wave Mode Conversion in a Pseudostreamer Structure

The Astrophysical Journal
The interaction of a fast magnetoacoustic wave with a magnetic null point in a pseudostreamer magnetic configuration is modeled. The incident fast wave is excited by an impulsive velocity driver located in the corona outside the Alfvén-acoustic ...

The Error Estimation of Transverse Coronal Loop Oscillation Parameters Based on Least Chi-squares Fitting

The Astrophysical Journal Supplement Series
Transverse oscillations of coronal loops not only influence coronal dynamics, but also provide a new perspective for coronal detection. To enhance their exploitation and utilization, accurately estimating the oscillation parameters is crucial.

Magnetohydrodynamic waves in structured atmospheres

, 2012
The effect of structuring, in the form of magnetic or density inhomogeneities, on the magnetohydrodynamic (mhd) waves of an infinite plasma is investigated.
