Non-Equilibrium Spectrum Formation Affecting Solar Irradiance

Solar and Stellar Astrophysics 2019-12-03 v3

Abstract

This is an overview of non-equilibrium aspects of the formation of solar continua and lines affecting the contributions by magnetic network and plage to spectrally resolved solar irradiance. After a brief summary of these contributions and a compact refresher of solar spectrum formation, the emphasis is on graphical exposition. Major obstacles for simulation-based irradiance studies are how to cope with NLTE scattering in the violet and ultraviolet line haze and how to cope with retarded hydrogen opacities in infrared and mm radiation.

Comments

Editor's Choice lead article of Solar Physics Topical Selection "Irradiance Variations of the Sun and Sun-like Stars". The arXiv pdf is better for e-reading because the publisher destroyed citation links and refused repair
