Quantifying scaling in the velocity field of the anisotropic turbulent solar wind [PDF]
, 2007 Solar wind turbulence is dominated by Alfvénic fluctuations with power spectral exponents that somewhat surprisingly evolve toward the Kolmogorov value of −5/3, that of hydrodynamic turbulence.

How Are the Abnormally Hot Chromosphere and Corona Heated by the Solar Magnetic Fields?
The Astrophysical JournalThe corona is a structure possessed by stars, including the Sun. The abnormal heating of the solar corona and chromosphere is one of the greatest mysteries in modern astronomy.

The Line Spectrum of the Solar Corona [PDF]
Publications of the Astronomical Society of the Pacific, 1945 For seventy years the solar corona has been observed at practically all eclipse expeditions. It consists of an approximately spherical halo, with faint streamers roughly radial in direction, extending a solar diameter or two from the photosphere, mainly from the spot zones. Curved rays also extend from the polar regions of the sun. The extent and shape

Topological structure of the magnetic solar corona
, 2007 The solar corona is a highly complex and active plasma environment, containing many exotic phenomena such as solar flares, coronal mass ejections, prominences, coronal loops, and bright points.

High-frequency Alfven waves in multi-ion coronal plasma : observational implications [PDF]
, 2005 We investigate the effects of high-frequency (of order ion gyrofrequency) Alfvén and ion-cyclotron waves on ion emission lines by studying the dispersion of these waves in a multi-ion coronal plasma.

Current sheets in the solar corona : formation, fragmentation and heating
, 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.

The solar corona during the total eclipse on 1806 June 16: graphical evidence of the coronal structure during the Dalton minimum [PDF]
, 2020 Visible coronal structure, in particular the spatial evolution of coronal streamers, provides indirect information about solar magnetic activity and the underlying solar dynamo.

Imaging the Solar Corona from “Within”: A Cutting-edge Approach to Enhance PSP/WISPR Imagery
The Astrophysical Journal Supplement SeriesThe unprecedented remote-sensing observations obtained by the Wide Field Imager for Solar Probe (WISPR) on board the Parker Solar Probe (PSP) from distances inside Mercury’s orbit are revolutionizing our perception of the fine-scale morphology and ...
