An extremely high velocity molecular jet surrounded by an ionized cavity in the protostellar source Serpens SMM1
Charles L. H. Hull, Josep M. Girart, Lars E. Kristensen +6
We report ALMA observations of a one-sided, high-velocity (80 km s) CO() jet powered by the intermediate-mass protostellar source Serpens SMM1-a.…
First detection of gas-phase ammonia in a planet-forming disk
Vachail N. Salinas, Michiel R. Hogerheijde, Edwin A. Bergin +10
Nitrogen chemistry in protoplanetary disks and the freeze-out on dust particles is key to understand the formation of nitrogen bearing species in early solar system analogs. So far…
Velocity-resolved hot water emission detected toward HL Tau with the Submillimeter Array
Lars E. Kristensen, Joanna M. Brown, David Wilner +1
Using the Submillimeter Array (SMA) on Mauna Kea, the H2-16O 10_2,9-9_3,6 transition (E_up=1863K) at 321.2 GHz has been detected toward the embedded low-mass protostar HL Tau. The…
WISH VI. Constraints on UV and X-ray irradiation from a survey of hydrides in low- to high-mass YSOs
A. O. Benz, S. Bruderer, E. F. van Dishoeck +18
Hydrides are simple compounds containing one or a few hydrogen atoms bonded to a heavier atom. They are fundamental precursor molecules in cosmic chemistry and many hydride ions ha…
Misalignment of Outflow Axes in the Proto-Multiple Systems in Perseus
Katherine I. Lee, Michael M. Dunham, Philip C. Myers +9
We investigate the alignment between outflow axes in nine of the youngest binary/multiple systems in the Perseus Molecular Cloud. These systems have typical member spacing larger t…
The Herschel-HIFI view of mid-IR quiet massive protostellar objects
F. Herpin, L. Chavarria, T. Jacq +9
We present Herschel/HIFI observations (WISH KP) of 14 water lines in a small sample of galactic massive protostellar objects: NGC6334I(N), DR21(OH), IRAS16272-4837, and IRAS05358+3…
Observations and modelling of CO and [CI] in disks. First detections of [CI] and constraints on the carbon abundance
M. Kama, S. Bruderer, M. Carney +23
The gas-solid budget of carbon in protoplanetary disks is related to the composition of the cores and atmospheres of the planets forming in them. The key gas-phase carbon carriers…
