Chromosphere of the quiet sun

Context. 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.

The multi-thermal chromosphere: Inversions of ALMA and IRIS data

, 2020
Context. Numerical simulations of the solar chromosphere predict a diverse thermal structure with both hot and cool regions. Observations of plage regions in particular typically feature broader and brighter chromospheric lines, which suggests that they ...

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.

The Bright Rim Prominences according to 2.5D Radiative Transfer

The Astrophysical Journal Letters
Solar prominences observed close to the limb commonly include a bright feature that, from the perspective of the observer, runs along the interface between itself and the underlying chromosphere. Despite several idealized models being proposed to explain

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?

Observations of the Formation and Disappearance of a Funnel Prominence

The Astrophysical Journal Letters
We present an observational study of the formation and disappearance of a funnel prominence. Before the funnel prominence formed, cool materials from the top of a preexisting polar crown prominence flowed along saddle-shaped coronal loops to their base ...
