The IRAM-30m line survey of the Horsehead PDR: II. First detection of the l-C3H+ hydrocarbon cation
Jérôme Pety, P. Gratier, V. Guzmán +9
We present the first detection of the l-C3H+ hydrocarbon in the interstellar medium. The Horsehead WHISPER project, a millimeter unbiased line survey at two positions, namely the p…
Herschel / HIFI observations of CO, H2O and NH3 in Mon R2
P. Pilleri, A. Fuente, J. Cernicharo +12
Context. Mon R2 is the only ultracompact HII region (UCHII) where the associated photon-dominated region (PDR) can be resolved with Herschel. Due to its brightness and proximity, i…
A Novel Semantic Software for Astronomical Concepts
M. Heydari-Malayeri, N. Moreau, F. Le Petit
We have created a new semantic tool called AstroConcepts, providing definitions of astronomical concepts present on Web pages. This tool is a Google Chrome plug-in that interrogate…
UV-driven chemistry in simulations of the interstellar medium. I. Post-processed chemistry with the Meudon PDR code
François Levrier, Franck Le Petit, Patrick Hennebelle +3
Our main purpose is to estimate the effect of assuming uniform density on the line-of-sight in PDR chemistry models, compared to a more realistic distribution for which total gas d…
Multi-line detection of O2 toward rho Oph A
R. Liseau, P. F. Goldsmith, B. Larsson +36
Models of pure gas-phase chemistry in well-shielded regions of molecular clouds predict relatively high levels of molecular oxygen, O2, and water, H2O. Contrary to expectation, the…
Surface chemistry in the interstellar medium - I - H2 formation by Langmuir-Hinshelwood and Eley-Rideal mechanisms
Jacques Le Bourlot, Franck Le Petit, Cecilia Pinto +2
H2 formation remains a major issue for the understanding of interstellar physics. We investigate H2 formation in the interstellar medium at the light of the most recent experimenta…
Herschel observations of interstellar chloronium
David A. Neufeld, Evelyne Roueff, Ronald L. Snell +21
Using the Herschel Space Observatory's Heterodyne Instrument for the Far-Infrared (HIFI), we have observed para-chloronium (H2Cl+) toward six sources in the Galaxy. We detected int…
