Circumstellar H2O in M-type AGB stars
2008 (English)In: Organic Matter in Space, 2008, 163-164 p.Conference paper (Other academic)
Surprisingly high amounts of H2O have recently been reported in the circumstellar envelope around the M-type AGB star W Hya. However, substantial uncertainties remain, as the required radiative transfer modelling is difficult due to high optical depths, sub-thermal excitation and the sensitivity to the combined radiation field from the central star and dust grains.
