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)…
