Stellar Model Chromospheres and Spectroscopic Diagnostics

Annual Review of Astronomy and Astrophysics, 2017
The discovery of exoplanets and the desire to understand their atmospheric chemical composition and habitability provides a new rationale for understanding the radiation from X-rays to radio wavelengths emitted by their host stars. Semiempirical models of stellar atmospheres that include accurate treatment of radiative transfer of all important atoms ...

A phenomenological interpretation of stellar chromospheres

Astrophysics and Space Science, 1986
An attempt is made to develop a phenomenological interpretation of stellar chromospheres. The following problems are examined: observed emission powers of ‘magnesium’ chromospheres on stars based on the ultraviolet doublet, 2800 Mgii, observations; dependence of chromosphere emission on spectral and luminosity classes; stellar chromospheres as an ...
