Chromosphere of the quiet sun

open access: yesAstronomy & 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.

The New Chromosphere [PDF]

open access: yes, 2007
. The natural state of the Solar chromosphere is very dynamic. Any photospheric disturbance will grow and naturally form shocks over the twenty scale-heights in density between the photosphere and the corona.

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

open access: yes
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 ...

Generation and Life Cycle of Solar Spicules

open access: yesThe Astrophysical Journal
The physical mechanism for the creation of solar spicules is proposed with three stages of their life cycle. It is assumed that at stage I the density hump is formed locally in the x-y plane in the lower chromosphere in the presence of temperature ...

Alfvén Wave Heating of Solar Chromosphere Reexamined

open access: yesThe 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
