Nitrogen isotopic ratios in Barnard 1: a consistent study of the N2H+, NH3, CN, HCN and HNC isotopologues
F. Daniel, M. Gerin, E. Roueff +7
The 15N isotopologue abundance ratio measured today in different bodies of the solar system is thought to be connected to 15N-fractionation effects that would have occured in the p…
Deep observations of O2 toward a low-mass protostar with Herschel-HIFI
Umut A. Yıldız, Kinsuk Acharyya, Paul F. Goldsmith +13
According to traditional gas-phase chemical models, O2 should be abundant in molecular clouds, but until recently, attempts to detect interstellar O2 line emission with ground- and…
A Herschel Study of D/H in Water in the Jupiter-Family Comet 45P/Honda-Mrkos-Pajdusakova and Prospects for D/H Measurements with CCAT
D. C. Lis, N. Biver, D. Bockelee-Morvan +11
We present Herschel observations of water isotopologues in the atmosphere of the Jupiter-family comet 45P/Honda-Mrkos-Pajdusakova. No HDO emission is detected, with a 3 sigma upper…
CH2D+, the Search for the Holy Grail
E. Roueff, M. Gerin, D. C. Lis +4
CH2D+, the singly deuterated counterpart of CH3+, offers an alternative way to mediate formation of deuterated species at temperatures of several tens of K, as compared to the rele…
Ionization toward the high-mass star-forming region NGC 6334 I
J. L. Morales Ortiz, C. Ceccarelli, D. C. Lis +3
Context. Ionization plays a central role in the gas-phase chemistry of molecular clouds. Since ions are coupled with magnetic fields, which can in turn counteract gravitational col…
Far-Infrared Spectroscopy of the Galactic Center. Hot Molecular Gas: Shocks versus Radiation near SgrA*
Javier R. Goicoechea, M. Etxaluze, J. Cernicharo +10
We present a 52-671um spectral scan toward SgrA* taken with the PACS and SPIRE spectrometers onboard Herschel. The achieved angular resolution allows us to separate, for the first…
