Circumstellar H2O in M-type AGB stars
Published online by Cambridge University Press: 01 February 2008
Abstract
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.
