The interstellar chemistry of H2C3O isomers
Jean-Christophe Loison, Marcelino Agúndez, Núria Marcelino +6
We present the detection of two H2C3O isomers, propynal and cyclopropenone, toward various starless cores and molecular clouds, together with upper limits for the third isomer prop…
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…
The peculiar distribution of CH3CN in IRC+10216 seen by ALMA
M. Agundez, J. Cernicharo, G. Quintana-Lacaci +4
IRC+10216 is a circumstellar envelope around a carbon-rich evolved star which contains a large variety of molecules. According to interferometric observations, molecules are distri…
Discovery of SiCSi in IRC+10216: A missing link between gas and dust carriers of SiC bonds
J. Cernicharo, M. C. McCarthy, C. A. Gottlieb +13
We report the discovery in space of a disilicon species, SiCSi, from observations between 80 and 350 GHz with the IRAM 30m radio telescope. Owing to the close coordination between…
Discovery of interstellar ketenyl (HCCO), a surprisingly abundant radical
Marcelino Agundez, Jose Cernicharo, Michel Guelin
We have conducted radioastronomical observations of 9 dark clouds with the IRAM 30m telescope. We present the first identification in space of the ketenyl radical (HCCO) toward the…
Si-bearing molecules towards IRC+10216: ALMA unveils the molecular envelope of CWLeo
L. Velilla Prieto, J. Cernicharo, G. Quintana-Lacaci +9
We report the detection during the ALMA Cycle 0 of SiS rotational lines in high-vibrational states as well as SiO and SiC lines in their ground vibrational state, towards IRC+1…
