Structure and dynamics of the internetwork solar chromosphere: Results of a small-scale dynamo simulation

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 ...

Turbulence and Its Potential Impact on Solar Chromospheric and Coronal Heating

The Astrophysical Journal
Low-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 ...

The quiet chromosphere: old wisdom, new insights, future needs [PDF]

, 2010
The introduction to this review summarizes chromosphere observation with two figures. The first part showcases the historical emphasis on the eclipse chromosphere in the development of NLTE line formation theory and criticizes 1D modeling.

Only binary stars can help us actually SEE a stellar chromosphere

, 2007
Binary stars of the \u3b6 Aurigae type (eclipsing systems containing a cool giant plus a hot mainsequence star) offer a unique and highly effective method of probing a stellar chromosphere.

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 ...
