Structure and dynamics of the solar chromosphere [PDF]

, 2002
The thesis "Structure and dynamics of the solar chromosphere" of J.M. Krijger is a study on the behavior of the solar chromosphere, the thin layer just above the solar surface (photosphere) visible in purple red light during a total solar eclipse.

On the Freeze‐In Distance of Solar Wind Fluid Entropy Variability in the Corona

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract The strong correlation between solar wind entropy and the frozen‐in ion charge state ratio O7+/O6+ ${\mathrm{O}}^{7+}/{\mathrm{O}}^{6+}$ indicates that entropy variability on timescales of hours or longer is preserved from its solar source. This prompts the question: where in the solar atmosphere does this entropy variability come from, and at

Dynamics of fine structure in the solar chromosphere [PDF]

, 2006
This thesis is concerned with the dynamics of fine structure of the solar chromosphere and transition region, in both quiet sun and active regions. It contains six chapters of observational studies.

MHD turbulence and heating of the open field-line solar corona [PDF]

, 2003
This paper discusses the possibility that heating of the solar corona in open field-line regions emanating from coronal holes is due to a nonlinear cascade, driven by low-frequency or quasi-static magnetohydrodynamic fluctuations.

Solar Activity Impacts on Ionospheric Scintillation and Precise Point Positioning Based on Multi‐Year GNSS and Scintillation Observations

Space Weather, Volume 24, Issue 3, March 2026.
Abstract Solar activity induces ionospheric irregularities that degrade Global Navigation Satellite System (GNSS) performance through amplitude and phase scintillation. Although numerous studies have investigated event‐driven or regional responses, the nonlinear coupling between solar radiation, ionospheric scintillation, and precise point positioning (

Measurement of Turbulence Injection Scale Down to the Chromosphere

The Astrophysical Journal Letters
The solar atmosphere displays a sharp temperature gradient, starting from spicules in the chromosphere at 2 × 10 ^4 K, outward into the corona exceeding ${10}^{6}$ K.
