Gallego, F. Tercero, J. A. López-Pérez, and P. de Vicente\\ reported on\\ **[[https://doi.org/10.1051/0004-6361/202140642|TMC-1, the starless core sulfur factory: Discovery of NCS, HCCS, H<sub>2</sub>CCS, H<sub>2</sub>CCCS, and C<sub>4</sub>S and detection of C<sub>5</sub>S]]**\\ //Astron. Astrophys.// **648**, Art. No. L3 (2021).\\ The ethenthionyl radical, HCCS, was identified through 2 <sup>1</sup>H hyperfine components of the <sup>2</sup>Π<sub>3/2</sub> //J// = 7/2 − 5/2 transition near 41.1 GHz in the course of a molecular line survey of the prototypical cold dark molecular cloud TMC-1 carried out with the Yebes 40 m radio telescope. The column density is slightly lower than that of H<sub>2</sub>CCS and about a factor of ten lower than that of HCS.\\ \\ R. Fuentetaja, M. Agúndez, C. Cabezas, B. Tercero, N. Marcelino, J. R.

Astrophys.// **667**, Art. No. L4 (2022).\\ Butatrienethionyl was detected through six consecutive transitions with 19/2 ≤ //J"// ≤ 29/2 between 31.0 and 50.3 GHz in the course of a molecular line survey of the prototypical cold dark molecular cloud TMC-1 carried out with the Yebes 40 m radio telescope. The column densities of HCS and HCCS are about factors of 58 and 7.2, respectively, higher than those of HC<sub>4</sub>S.\\ \\ ---- Contributor(s): H. S. P.
