Origin of warm and hot gas emission from low-mass protostars: Herschel-HIFI observations of CO J=16-15. I. Line profiles, physical conditions, and H2O abundance
L. E. Kristensen, E. F. van Dishoeck, J. C. Mottram +18
(Abridged) Through spectrally unresolved observations of high-J CO transitions, Herschel-PACS has revealed large reservoirs of warm (300 K) and hot (700 K) molecular gas around low…
Water delivery from cores to disks: deuteration as a probe of the prestellar inheritance of H2O
K. Furuya, M. N. Drozdovskaya, R. Visser +5
We investigate the delivery of regular and deuterated forms of water from prestellar cores to circumstellar disks. We adopt a semi-analytical axisymmetric two-dimensional collapsin…
Water in Low-Mass Star-Forming Regions with Herschel: The Link Between Water Gas and Ice in Protostellar Envelopes
M. Schmalzl, R. Visser, C. Walsh +4
Aims: Our aim is to determine the critical parameters in water chemistry and the contribution of water to the oxygen budget by observing and modelling water gas and ice for a sampl…
Isotope selective photodissociation of N2 by the interstellar radiation field and cosmic rays
Alan N. Heays, Ruud Visser, Roland Gredel +4
Photodissociation of 14N2 and 14N15N occurs in interstellar clouds, circumstellar envelopes, protoplanetary discs, and other environments due to UV radiation from stellar sources a…
Deuterated water in the solar-type protostars NGC 1333 IRAS 4A and IRAS 4B
A. Coutens, C. Vastel, S. Cabrit +19
Aims. The aim of this paper is to study deuterated water in the solar-type protostars NGC1333 IRAS4A and IRAS4B, to compare their HDO abundance distribution with other star-forming…
Waterfalls around protostars: Infall motions towards Class 0/I envelopes as probed by water
J. C. Mottram, E. F. van Dishoeck, M. Schmalzl +4
Abridged abstract: For stars to form, material must fall inwards from core scales through the envelope towards the central protostar. The velocity profile around protostars is poor…
