Photospheric Temperatures from Ca II H
2010 (English)In: Magnetic Coupling between the Interior and Atmosphere of the Sun / [ed] S.S. Hasan, R.J. Rutten, Springer , 2010Conference paper (Other academic)
The temperature stratification in the upper photosphere can be extracted from Ca II H&K spectrograms following Shine and Linsky (1974) by assuming LTE, the Eddington-Barbier approximation, hydrostatic equilibrium, and that Ca II is mostly in the ground state. Rouppe van der Voort (2002) confirmed that these assumptions were solid for a wide range in the Ca IIK wings and further developed the method including forward computation using MULTI (Carlsson 1986).
