Far-infrared molecular lines from Low- to High-Mass Star Forming Regions observed with Herschel
A. Karska, F. Herpin, S. Bruderer +13
(Abridged) We study the response of the gas to energetic processes associated with high-mass star formation and compare it with studies on low- and intermediate-mass young stellar…
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…
Probing the Turbulent Ambipolar Diffusion Scale in Molecular Clouds with Spectroscopy
Talayeh Hezareh, Timea Csengeri, Martin Houde +2
We estimate the turbulent ambipolar diffusion length scale and magnetic field strength in the massive dense cores CygX-N03 and CygX-N53, located in the Cygnus-X star-forming region…
Water in star-forming regions with Herschel (WISH). IV. A survey of low-J H2O line profiles toward high-mass protostars
Floris van der Tak, Luis Chavarria, Fabrice Herpin +4
To understand the origin of water line emission and absorption during high-mass star formation, we decompose high-resolution Herschel-HIFI line spectra toward 19 high-mass star-for…
Water in star forming regions with Herschel (WISH) III. Far-infrared cooling lines in low-mass young stellar objects
A. Karska, G. J. Herczeg, E. F. van Dishoeck +22
(Abridged) Far-infrared Herschel-PACS spectra of 18 low-mass protostars of various luminosities and evolutionary stages are studied. We quantify their far-infrared line emission an…
Herschel-HIFI observations of high-J CO and isotopologues in star-forming regions: from low- to high-mass
I. San Jose-Garcia, J. C. Mottram, L. E. Kristensen +9
Context; Our understanding of the star formation process has traditionally been confined to certain mass or luminosity boundaries because most studies focus only on low-, intermedi…
