Constraints on Acoustic Wave Energy Fluxes and Radiative Losses in the Solar Chromosphere from Non-LTE Inversions

The Astrophysical Journal
Accurately assessing the balance between acoustic wave energy fluxes and radiative losses is critical for understanding how the solar chromosphere is thermally regulated.

Turbulence in the Chromosphere

Publications of the Astronomical Society of Japan, 1962
Abstract Turbulence velocities in the chromosphere were determined from the base up to 10,000 km. Measurement was made on flash spectrograms of 1958 eclipse in South Pacific. The dispersion was about 2.3 A/mm and the resolution in terms of velocity was 2–3 km/sec in most probable velocity ξ0.

Calcium Bright Knots and the Formation of Chromospheric Anemone Jets on the Sun

The Astrophysical Journal Letters
Space-based observations show that the solar atmosphere from the solar chromosphere to the solar corona is filled with small-scale jets and is linked with small-scale explosions.

Measurement of Turbulence Injection Scale Down to the Chromosphere

The Astrophysical Journal Letters
The solar atmosphere displays a sharp temperature gradient, starting from spicules in the chromosphere at 2 × 10 ^4 K, outward into the corona exceeding ${10}^{6}$ K.
