Ultra-deep 31.0-50.3 GHz spectral survey of IRC+10216
J. R. Pardo, J. Cernicharo, B. Tercero +8
Context. IRC+10216, the carbon-rich envelope of the asymptotic giant branch (AGB) star CW Leo, is one of the richest molecular sources in the sky. Available spectral surveys below…
TMC-1, the starless core sulfur factory: Discovery of NCS, HCCS, H2CCS, H2CCCS, and C4S and detection of C5S
J. Cernicharo, C. Cabezas, M. Agundez +7
We report the detection of the sulfur-bearing species NCS, HCCS, H2CCS, H2CCCS, and C4S for the first time in space. These molecules were found towards TMC-1 through the observatio…
Discovery of the propargyl radical (CH2CCH) in TMC-1: one of the most abundant radicals ever found and a key species for cyclization to benzene in cold dark clouds
M. Agundez, C. Cabezas, B. Tercero +4
We present the first identification in interstellar space of the propargyl radical (CH2CCH). This species was observed in the cold dark cloud TMC-1 using the Yebes 40m telescope. T…
Discovery of allenyl acetylene, H2CCCHCCH, in TMC-1. A study of the isomers of C5H4
J. Cernicharo, C. Cabezas, M. Agundez +7
We present the discovery in TMC-1 of allenyl acetylene, H2CCCHCCH, through the observation of nineteen lines with a signal-to-noise ratio ~4-15. For this species, we derived a rota…
Discovery of CH2CHCCH and detection of HCCN, HC4N, CH3CH2CN, and, tentatively, CH3CH2CCH in TMC-1
J. Cernicharo, M. Agundez, C. Cabezas +7
We present the discovery in TMC-1 of vinyl acetylene, CH2CHCCH, and the detection, for the first time in a cold dark cloud, of HCCN, HC4N, and CH3CH2CN. A tentative detection of CH…
Space and laboratory discovery of HC3S+
J. Cernicharo, C. Cabezas, Y. Endo +5
We report the detection in TMC-1 of the protonated form of C3S. The discovery of the cation HC3S+ was carried through the observation of four harmonically related lines in the Q ba…
Tentative detection of HC5NH+ in TMC-1
N. Marcelino, M. Agundez, B. Tercero +5
Using the Yebes 40m radio telescope, we report the detection of a series of seven lines harmonically related with a rotational constant B0=1295.81581 +/- 0.00026 MHz and a distorti…
28 SiO v=0 J=1-0 emission from evolved stars
P. de Vicente, V. Bujarrabal, A. Díaz-Pulido +18
Observations of 28SiO v=0 J=1-0 line emission (7-mm wavelength) from AGB stars show in some cases peculiar profiles, composed of a central intense component plus a wider plateau. V…
Probing non polar interstellar molecules through their protonated form: Detection of protonated cyanogen (NCCNH+)
M. Agundez, J. Cernicharo, P. de Vicente +19
Cyanogen (NCCN) is the simplest member of the series of dicyanopolyynes. It has been hypothesized that this family of molecules can be important constituents of interstellar and ci…
