Water in massive star-forming regions with the Herschel Space Observatory
Fabrice Herpin,L. Chavarria,F. F. S. van der Tak,Friedrich Wyrowski,Sylvain Bontemps,E. F. van Dishoeck +5 more
TL;DR: In this paper, the first results of the WISH program, dedicated to the water study in star-forming regions with Herschel, concerning the massive star forming regions were presented.
WISH VI. Constraints on UV and X-ray irradiation from a survey of hydrides in low- to high-mass YSOs
Arnold O. Benz,Simon Bruderer,E. F. van Dishoeck,M. Melchior,S. F. Wampfler,F. F. S. van der Tak,Javier R. Goicoechea,Nick Indriolo,Lars E. Kristensen,Darek Lis,Joseph C. Mottram,Edwin Bergin,Paola Caselli,Fabrice Herpin,Michiel R. Hogerheijde,Doug Johnstone,René Liseau,Brunella Nisini,M. Tafalla,Ruud Visser,Friedrich Wyrowski +20 more
TL;DR: In this paper, column density ratios of CH+/OH+ are estimated from chemical slab models, assuming that the H2 density is given by the specific density model of each object at the beam radius.
Journal ArticleDOI
Observations of water with Herschel/HIFI toward the high-mass protostar AFGL 2591
Yunhee Choi,F. F. S. van der Tak,E. F. van Dishoeck,Fabrice Herpin,Fabrice Herpin,Friedrich Wyrowski +5 more
TL;DR: In this paper, the authors used spectrally resolved observations of rotational lines of H$_2$O and its isotopologs with Herschel/HIFI to constrain the physical conditions of the water emitting region toward the high-mass protostar AFGL2591.

Hot Molecular Cores and High-Mass Star Formation
TL;DR: In this article, a review of hot cores in the context of high-mass star formation is presented, where the authors give an overview of chemical processes and diversity during high mass star formation and review the ''warm envelope'' phase which probably precedes the formation of hot core.
Journal ArticleDOI
Tracing high energy radiation with molecular lines near deeply embedded protostars
P. Stäuber,Arnold O. Benz,Jes K. Jørgensen,E. F. van Dishoeck,Steven D. Doty,F. F. S. van der Tak +5 more
TL;DR: In this paper, the James Clerk Maxwell Telescope (JCMT) was used to observe the submillimeter lines of CN, NO, CO+ and SO+ in two high-mass and up to nine low-mass young stellar objects and compared with chemical models.
