Water deuterium fractionation in the high-mass star-forming region G34.26+0.15 based on Herschel/HIFI data
Water deuterium fractionation in the high-mass star-forming region G34.26+0.15 based on Herschel/HIFI data
Understanding water deuterium fractionation is important for constraining the mechanisms of water formation in interstellar clouds. Observations of HDO and H|$_2^{18}$|O transitions were carried out towards the high-mass star-forming region G34.26+0.15 with the Heterodyne Instrument for the Far-Infrared (HIFI) instrument onboard the Herschel Space Observatory, as well as with ground-based …
