A Unified Model of Solar Prominence Formation with Self-consistent Heating
The Astrophysical JournalSeveral models have been proposed to explain the formation of solar prominences, among which the evaporation–condensation model and the direct injection model are the most popular ones.

LIII. Ionization in the solar chromosphere [PDF]
The London, Edinburgh, and Dublin Philosophical Magazine and Journal of Science, 1920 1. 1. In the present paper it has been shown from a discussion of the high-level chromospheric spectrum that this region is chiefly composed of ionized atoms of Calcium, Barium, Strontium, Scandium...

Simulations of Alfvén and Kink wave driving of the solar chromosphere : efficient heating and spicule launching [PDF]
, 2016 Two of the central problems in our understanding of the solar chromosphere are how the upper chromosphere is heated and what drives spicules. Estimates of the required chromospheric heating, based on radiative and conductive losses, suggest a rate of ~0 ...

Modeling the Solar Chromosphere
, 2007 Spectral diagnostic features formed in the solar chromosphere are few and difficult to interpret -- they are neither formed in the optically thin regime nor in local thermodynamic equilibrium (LTE). To probe the state of the chromosphere, both from observations and theory, it is therefore necessary with modeling.

Turbulence and Its Potential Impact on Solar Chromospheric and Coronal Heating
The Astrophysical JournalLow-frequency turbulence in the solar chromosphere remains poorly understood. We address (1) the sources of low-frequency turbulence that potentially heat the chromosphere, and (2) how turbulence is transported and dissipated throughout the chromosphere ...

A single frequency approach to nonequilibrium modeling of the chromosphere
Astronomy & AstrophysicsContext. The solar chromosphere is a region where radiation plays a critical role in energy transfer and interacts strongly with the plasma. In this layer, strong spectral lines, such as the Lyman lines, contribute significantly to radiative energy ...

The differential rotation of the chromosphere and the quiet chromosphere in the falling and rising period of a solar cycle [PDF]
The full-disk chromosphere was routinely monitored in the He I 10830\AA\, line at the National Solar Observatory/Kitt Peak from 2004 Nov. to 2013 March, and thereby, synoptic maps of He I line intensity from Carrington rotations 2032 to 2135 were ...
