The solar chromosphere and corona: Quiet sun
Abstract
This volume treats the chromosphere and corona of the quiet sun as a unified topic, stressing their common origin in the mechanical-energy flux generated in the hydrogen convection zone beneath the photosphere. It is noted at the outset that the sharply different physical regimes occurring in the corona and the chromosphere are related to the response of the atmosphere to the mechanical-energy input rather than to fundamentally different mechanisms of energy input. A broad overview of the methods and objectives of chromospheric and coronal studies is presented, and analytical methods for interpreting spectroscopic data are described. The major questions dealt with include structures observed in the photosphere, chromosphere, and corona; macroscopic motions in the solar atmosphere; solar magnetic-field phenomena; spectral characteristics of the chromosphere and corona; analyses of IR, radio, and XUV spectral data; empirical models of the chromosphere and corona; the chromospheric structure inferred from spectral lines; wave generation in the sun; and heating of the chromosphere and corona.
