Soft X-ray heating of the solar chromosphere during the gradual phase of two solar flares

, 2004
In this paper we perform an analysis of the energetics of the solar flaring chromosphere irradiated by soft X-rays (SXR) emitted from overlying hot flare loops.

Solar Chromospheric Heating by Magnetohydrodynamic Waves: Dependence on the Inclination of the Magnetic Field

The Astrophysical Journal
A proposed mechanism for solar chromospheric heating is magnetohydrodynamic waves propagating upward along magnetic field lines and dissipating their energy in the chromosphere.

Comparison between variations in solar UV radiation and sunspot parameters with Mg II daily index as a proxy

Physics Open
Solar UV radiation influence the Earth's climate and upper atmosphere. The UV emission from the Sun modulates with the sunspot cycle with an 11-year periodicity.

Chromosphere of the quiet sun

Astronomy & Astrophysics
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.

Propagation and energy dissipation of shock waves in the solar chromosphere [PDF]

The solar atmosphere is permeated by various types of waves that originate from subsurface convection. As these waves propagate upward, they encounter they encounter a steep decrease in the density of the medium, leading to their steepening into shock ...

Alfvén Wave Heating of Solar Chromosphere Reexamined

The Astrophysical Journal
Models of heating the weakly ionized solar atmosphere by collisional damping of upward-propagating Alfvén waves, calculated under the assumption that only incompressible (intermediate-mode) MHD waves are involved, have predicted heating rates that do not
