NLTE water lines in Betelgeuse-like atmospheres
The interpretation of water lines in red supergiant stellar atmospheres has been much debated over the past decade. The introduction of the so-called MOLspheres to account for near-infrared “extra” absorption has been controversial. We propose that non-LTE effects should be taken into account before considering any extra-photospheric contribution.
