The Non-Magnetic Solar Chromosphere
, 2007 . We summarize recent results from self-consistent non-LTE radiation hydrodynamicssimulations of the propagation of acoustic waves through the non-magnetic solar chromosphere. References to more detailed write-ups of the work are given.

Analysis of OSO data to determine the structure and energy balance of the solar chromosphere [PDF]
, 1975 A detailed reexamination of the temperature-density structure of the photosphere and low chromosphere shows that the middle and upper chromosphere, which directly emits most of the OSO spectrum, is sensitive to conditions in this underlying region of the

Near-ultraviolet Spectropolarimetry as a Tracer of Magnetic Markers of Flux Rope Formation
The Astrophysical JournalWe investigate the suitability of the combined spectral windows of Mg ii h and k and the Fe ii lines around 261 nm as magnetic markers of filament formation.

Context. The heating and structure of the solar chromosphere depends on the underlying magnetic field, among other parameters. The lowest magnetic flux of the solar atmosphere is found in the quiet Sun internetwork and is thought to be provided by the ...

Solar Flare Ribbon Fronts. II. Evolution of Heating Rates in Individual Flare Footpoints
The Astrophysical JournalSolar flare ribbon fronts appear ahead of the bright structures that normally characterize solar flares, and can persist for an extended period of time in spatially localized patches before transitioning to “regular” bright ribbons. They likely represent

The Astrophysical JournalA proposed mechanism for solar chromospheric heating is magnetohydrodynamic waves propagating upward along magnetic field lines and dissipating their energy in the chromosphere.

Astronomy & AstrophysicsContext. The solar chromosphere is a dynamic and crucial interface between the solar interior and its interplanetary environment, regulating how energy is locally deposited into heat and transported into the upper atmospheric layers.

Soft X-ray heating of the solar chromosphere during the gradual phase of two solar flares
, 2004 In this paper we perform an analysis of the energetics of the solar flaring chromosphere irradiated by soft X-rays (SXR) emitted from overlying hot flare loops.
