<i>J</i>, <i>H</i>, <i>K</i> spectro-interferometry of the Mira variable S Orionis
Aims.We present J, H, K spectrally dispersed interferometry with a spectral resolution of 35 for the Mira variable S Orionis. We aim at measuring the diameter variation as a function of wavelength that is expected due to molecular layers lying above the continuum-forming photosphere. Our final goal is a better …
