Confirmation of the outflow in L1451-mm: SiO line and CHOH maser detections
V. Wakelam, A. Coutens, P. Gratier +2
The observational counterparts of theoretically predicted first hydrostatic cores (FHSC) have been searched for in the interstellar medium for nearly two decades now. Distinguishin…
New constraints on the initial parameters of low-mass star formation from chemical modeling
Thomas H. G. Vidal, Pierre Gratier, Neil Vaytet +2
The complexity of physico-chemical models of star formation is increasing, with models that take into account new processes and more realistic setups. These models allow astrochemi…
Methyl cyanide (CH3CN) and propyne (CH3CCH) in the low mass protostar IRAS 16293-2422
Ines Andron, Pierre Gratier, Liton Majumdar +4
Methyl cyanide (CH3CN) and propyne (CH3CCH) are two molecules commonly used as gas thermometers for interstellar gas. They are detected in several astrophysical environments and in…
Gas phase Elemental abundances in Molecular cloudS (GEMS) I. The prototypical dark cloud TMC 1
A. Fuente, D. Navarro, P. Caselli +30
GEMS is an IRAM 30m Large Program whose aim is determining the elemental depletions and the ionization fraction in a set of prototypical star-forming regions. This paper presents t…
Sulphur chemistry in the L1544 pre-stellar core
Charlotte Vastel, David Quénard, Romane Le Gal +7
The L1544 pre-stellar core has been observed as part of the ASAI IRAM 30m Large Program as well as follow-up programs. These observations have revealed the chemical richness of the…
First detection of interstellar S2H
Asunción Fuente, Javier R. Goicoechea, Jerome Pety +11
We present the first detection of gas phase S2H in the Horsehead, a moderately UV-irradiated nebula. This confirms the presence of doubly sulfuretted species in the interstellar me…
