Detection of the linear SiC and SiC radicals in IRC\,+10216
José Cernicharo, Juan Ramón Pardo, Marcelino Agúndez +6
We detected the linear radicals SiC and SiC toward IRC+10216 using an ultrasensitive line survey gathered with the Yebes 40\,m radio telescope. The derived column d…
Cumulene carbenes in TMC-1: Astronomical discovery of -HC
C. Cabezas, B. Tercero, M. Agúndez +4
We report the first detection in space of the cumulene carbon chain -HC. A total of eleven rotational transitions, with = 7-10 and = 0 and 1, were detecte…
Discovery of HC4NC in TMC-1: A study of the isomers of HC3N, HC5N, and HC7N
J. Cernicharo, N. Marcelino, M. Agundez +4
We present a study of the isocyano isomers of the cyanopolyynes HC3N, HC5N, and HC7N in TMC-1 and IRC+10216 carried out with the Yebes 40m radio telescope. This study has enabled u…
Interstellar nitrile anions: Detection of C3N- and C5N- in TMC-1
J. Cernicharo, N. Marcelino, J. R. Pardo +5
We report on the first detection of C3N- and C5N- towards the cold dark core TMC-1 in the Taurus region, using the Yebes 40 m telescope. The observed C3N/C3N- and C5N/C5N- abundanc…
Discovery of the first Ca-bearing molecule in space: CaNC
J. Cernicharo, L. Velilla-Prieto, M. Agúndez +6
We report on the detection of calcium isocyanide, CaNC, in the carbon-rich evolved star IRC+10216. We derived a column density for this species of (2.00.5)10 cm…
The maser emitting structure and time variability of the SiS lines J=14-13 and 15-14 in IRC+10216
J. P. Fonfría, M. Fernández-López, J. R. Pardo +8
We present new high angular resolution interferometer observations of the v=0 J=14-13 and 15-14 SiS lines towards IRC+10216, carried out with CARMA and ALMA. The maps, with angular…
Clues to NaCN formation
G. Quintana-Lacaci, J. Cernicharo, L. Velilla Prieto +5
ALMA is providing us essential information on where certain molecules form. Observing where these molecules emission arises from, the physical conditions of the gas, and how this r…
CHESS, Chemical Herschel surveys of star forming regions:Peering into the protostellar shock L1157-B1
B. Lefloch, S. Cabrit, C. Codella +74
The outflow driven by the low-mass class 0 protostar L1157 is the prototype of the so-called chemically active outflows. The bright bowshock B1 in the southern outflow lobe is a pr…
A line confusion limited millimeter survey of Orion KL (I): sulfur carbon chains
B. Tercero, J. Cernicharo, J. R. Pardo +1
We perform a sensitive (line confusion limited), single-side band spectral survey towards Orion KL with the IRAM 30m telescope, covering the following frequency ranges: 80-115.5 GH…
Star Formation in the Trifid Nebula
B. Lefloch, J. Cernicharo, J. R. Pardo
We have obtained maps of the 1.25mm thermal dust emission and the molecular gas emission over a region of 20' by 10' arcmin around the Trifid Nebula (M20), with the IRAM 30m and th…
