Formation of the Methyl Cation by Photochemistry in a Protoplanetary Disk
Olivier Berné, Marie-Aline Martin-Drumel, Ilane Schroetter +53
Forty years ago it was proposed that gas phase organic chemistry in the interstellar medium was initiated by the methyl cation CH3+, but hitherto it has not been observed outside t…
Aromatic cycles are widespread in cold clouds
M. Agundez, N. Marcelino, B. Tercero +1
We report the detection of large hydrocarbon cycles toward several cold dense clouds. We observed four sources (L1495B, Lupus-1A, L483, and L1527) in the Q band (31-50 GHz) using t…
PDRs4All IV. An embarrassment of riches: Aromatic infrared bands in the Orion Bar
Ryan Chown, Ameek Sidhu, Els Peeters +136
(Abridged) Mid-infrared observations of photodissociation regions (PDRs) are dominated by strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs ar…
Laboratory and astronomical discovery of the cyanovinyl radical H2CCCN
C. Cabezas, J. Tang, M. Agúndez +9
We report the first laboratory and interstellar detection of the alpha-cyano vinyl radical (H2CCCN). This species was produced in the laboratory by an electric discharge of a gas m…
The abundance and excitation of molecular anions in interstellar clouds
M. Agundez, N. Marcelino, B. Tercero +2
We report new observations of molecular anions with the Yebes 40m and IRAM 30m telescopes toward the cold dense clouds TMC-1 CP, Lupus-1A, L1527, L483, L1495B, and L1544. We detect…
Discovery of HCCCH in TMC-1
W. G. D. P. Silva, J. Cernicharo, S. Schlemmer +13
Based on a novel laboratory method, 14 mm-wave lines of the molecular ion HCCCH have been measured in high resolution, and the spectroscopic constants of this asymmetric ro…
