PREDICTED ULTRAVIOLET SPECTRA FROM STELLAR CHROMOSPHERES

open access: closedJournal of Quantitative Spectroscopy and Radiative Transfer, 1968
Abstract Perhaps the most tangible evidence of the existence and structure of postulated stellar chromospheres of otherwise relatively cool stars would be the detection of an intense ultraviolet spectrum. The solar case for which a variety of measurements is available now reveals that the observed spectrum depends in a very complex and not thoroughly

A phenomenological interpretation of stellar chromospheres

open access: closedAstrophysics 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 ...

Solar and stellar chromospheric contrast

Solar Physics, 1994
We present an analysis of disk-integrated spectra of the Caii K line (3933.68 A). The selection of parameters in the line profile, and the correlations between them, follow the work of Smith (1960), but represent an innovative aspect in the fact that our data are spatially integrated.
