Radiation Shock Dynamics In The Solar Chromosphere -- Results Of Numerical Simulations

open access: yes, 2007
. We report results from self-consistent non-LTE radiation hydrodynamics simulations of the propagation of acoustic waves through the solar chromosphere. It is found that enhanced chromospheric emission, which corresponds to an outwardly increasing semi-

The solar chromosphere at high resolution with IBIS. IV. Dual-line evidence of heating in chromospheric network

open access: yes, 2009
The structure and energy balance of the solar chromosphere remain poorly known.We used the imaging spectrometer IBIS at the Dunn Solar Telescope to obtain fast-cadence, multi-wavelength profile sampling of Hα and Ca II 854.2 nm over a sizable two ...

Realistic Modeling of Interaction of Quiet-Sun Magnetic Fields with the Chromosphere

open access: yes, 2017
Highresolution observations and 3D MHD simulations reveal intense interaction between the convection zone dynamics and the solar atmosphere on subarcsecond scales.

Dynamics of magnetized vortex tubes in the solar chromosphere

open access: yes, 2020
We use three-dimensional radiative MHD simulations to investigate the formation and dynamics of small-scale (less than 0.5 Mm in diameter) vortex tubes spontaneously generated by turbulent convection in quiet-Sun regions with an initially weak (10 G ...

Log-normal intensity distribution of the quiet-Sun FUV continuum observed by SUMER

open access: yes, 2007
We analyse observations of the quiet-Sun far ultraviolet (FUV) continuum at various wavelengths near 1430 Å obtained by the SUMER instrument on SOHO.
