Waves in the Chromosphere: Observations [PDF]
, 2003 I review the literature on observational aspects of waves in the solar chromosphere in the first part of this contribution. High-frequency waves are invoked to build elaborate cool-star chromosphere heating theories but have not been detected decisively so far, neither as magnetic modes in network elements nor as acoustic modes in below-the-canopy ...

3-D hydrodynamic simulations of the solar chromosphere
, 2020 . We present first results of three-dimensional numerical simulations of the non-magnetic solar chromosphere, computed with the radiation hydrodynamics code CO 5 BOLD.

Observations of the upper solar chromosphere with SUMER
, 2003 The structure and dynamics of the solar chromosphere are still matters of debate. The chromospheric network reflecting the supergranulation of the outer convection zone of the Sun is a prominent feature of the lower solar atmosphere that extends into the

Collisional dissipation of Alfvén waves in a partially ionised solar chromosphere [PDF]
, 2005 Certain regions of the solar atmosphere are at sufficiently low temperatures to be only partially ionised. The lower chromosphere contains neutral atoms, the existence of which greatly increases the efficiency of the damping of waves due to collisional ...

What Happens in “Chromospheres”?
Stem Cells Translational Medicine, 2013 The recent paper by Santana et al. titled “Isolation, Characterization, and Differentiation of Progenitor Cells From Adult Human Adrenal Medulla” [1] is an interesting contribution to human chromaffin cell biology. However, I am concerned about omissions of important information in the literature that could lead to alternate interpretations of the ...

Magnetic flux emergence into the solar photosphere and chromosphere
, 2009 Aims. We model the emergence of magnetized plasma across granular convection cells and the low atmosphere, including layers up to the mid-chromosphere. Methods.

Multi-height spectropolarimetric signatures of magnetoacoustic waves in solar plage
Frontiers in Astronomy and Space SciencesWe analyze high-cadence spectropolarimetric observations of solar plage obtained with the Visible Spectro-Polarimeter on the Daniel K. Inouye Solar Telescope (DKIST) to investigate low-chromospheric waves sampled by the Na I D1 5896 Å and Ca II 8542 Å ...

Hydrogen Atmospheres in the Absence of Thermodynamic Equilibrium. IV. The Solar Chromosphere
, 1948 A discussion of the observational data shows that in the range 0<z<2.5 x 108 cm. the electron concentration in the lower chromosphere may be expressed as Ne=5x 1011 exp(-6 x 10-9z) per cc., where z cm. is the height measured from a level 500 km.

Propagation of alfvénic waves from corona to chromosphere and consequences for solar flares
, 2013 How do magnetohydrodynamic waves travel from the fully ionized corona, into and through the underlying partially ionized chromosphere, and what are the consequences for solar flares?
