High-J CO survey of low-mass protostars observed with Herschel-HIFI
Umut A. Yıldız, Lars E. Kristensen, Ewine F. van Dishoeck +8
The evolution of deeply embedded young stellar objects (YSOs) has traditionally been traced through dust continuum spectral energy distributions (SEDs), but the use of CO excitatio…
Improved determination of the 1(0)-0(0) rotational frequency of NH3D+ from the high resolution spectrum of the v4 infrared band
J. L. Doménech, M. Cueto, V. J. Herrero +4
The high resolution spectrum of the v4 band of NH3D+ has been measured by difference frequency IR laser spectroscopy in a multipass hollow cathode discharge cell. From the set of m…
Detection of the Ammonium Ion in Space
J. Cernicharo, B. Tercero, A. Fuente +9
We report on the detection of a narrow feature at 262816.73 MHz towards Orion and the cold prestellar core B1-bS, that we attribute to the 1(0)-0(0) line of the deuterated Ammonium…
The Herschel/HIFI spectral survey of OMC-2 FIR 4 (CHESS): An overview of the 480 to 1902 GHz range
M. Kama, A. López-Sepulcre, C. Dominik +6
Broadband spectral surveys of protostars offer a rich view of the physical, chemical and dynamical structure and evolution of star-forming regions. The Herschel Space Observatory o…
Probing the role of polycyclic aromatic hydrocarbons in the photoelectric heating within photodissociation regions
Yoko Okada, Paolo Pilleri, Olivier Berné +8
We observationally investigate the relation between the photoelectric heating efficiency in PDRs and the charge of PAHs, which are considered to play a key role in photoelectric he…
