Synthetic spectra of SiO first overtone bandheads in different cool stars. The effects of applying spherical or plane parallel radiative transfer are shown. All models have solar mass and chemical abundances. Synthetic spectra of SiO first overtone bandheads in cool giants. In addition the effects of applying spherical or plane parallel radiative transfer are shown.
All models have solar mass and chemical abundances.
Models have been calculated with and without including water lines. Effect of water opacity on synthetic spectra. In the lower panel two synthetic spectra for the same wavelength range are shown. In the lower panel two synthetic spectra for the same wavelength range are shown.
