Discovery of the elusive thioketenylium, HCCS+, in TMC-1
C. Cabezas, M. Agundez, N. Marcelino +6
We report the detection in TMC-1 of the cation HCCS+ (3Sigma-), which is the protonated form of the widespread radical CCS. This is the first time that a protonated radical has bee…
New deuterated species in TMC-1: Detection of CH2DC4H with the QUIJOTE line survey
C. Cabezas, R. Fuentetaja, E. Roueff +6
We report the first detection in space of the single deuterated isotopologue of methyldiacetylene, CH2DC4H. A total of 12 rotational transitions, with J = 8-12 and Ka = 0 and 1, we…
Detection of the propargyl radical at lambda 3 mm
M. Agundez, N. Marcelino, C. Cabezas +4
We report the detection of the propargyl radical (CH2CCH) in the cold dark cloud TMC-1 in the lambda 3 mm wavelength band. We recently discovered this species in space toward the s…
Discovery of HCCCO and C5O in TMC-1 with the QUIJOTE line survey
J. Cernicharo, M. Agundez, C. Cabezas +5
We report on the detection, for the first time in space, of the radical HCCCO and of pentacarbon monoxide, C5O. The derived column densities are (1.6+/-0.2)e11 cm-2 and (1.5+/-0.2)…
Discovery of two isomers of ethynyl cyclopentadiene in TMC-1: Abundances of CCH and CN derivatives of hydrocarbon cycles
J. Cernicharo, M. Agundez, R. I. Kaiser +5
We report the detection of two isomers of ethynyl cyclopentadiene (c-C5H5CCH), namely 1- and 2-ethynyl-1,3-cyclopentadiene, in the direction of TMC-1. We derive column densities of…
Discovery of benzyne, o-C6H4, in TMC-1 with the QUIJOTE line survey
J. Cernicharo, M. Agundez, R. I. Kaiser +5
We report the detection, for the first time in space, of a new non-functionalised hydrocarbon cycle in the direction of TMC-1: o-C6H4 (ortho-benzyne). We derive a column density fo…
