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 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…
Yebes 40 m radio telescope and the broad band NANOCOSMOS receivers at 7 mm and 3 mm for line surveys
F. Tercero, J. A. López-Pérez, J. D. Gallego +23
Yebes 40\,m radio telescope is the main and largest observing instrument at Yebes Observatory and it is devoted to Very Long Baseline Interferometry (VLBI) and single dish observat…
Using radio astronomical receivers for molecular spectroscopic characterization in astrochemical laboratory simulations: A proof of concept
I. Tanarro, B. Alemán, P. de Vicente +26
We present a proof of concept on the coupling of radio astronomical receivers and spectrometers with chemical reactorsand the performances of the resulting setup for spectroscopy a…
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…
