A quest for sulfur-bearing refractory species. Identification of CaS in the interstellar medium
A. Tasa-Chaveli, Ã. Sánchez-Monge, A. Fuente +10
The recent detection of refractory molecules in massive star-forming regions provides a means of probing the innermost regions of disks around massive stars. These detections also…

Gas-phase Elemental abundances in Molecular cloudS (GEMS) XI. The evolution of HCN, HNC, and N2H+ isotopic ratios in starless cores
A. Tasa-Chaveli, A. Fuente, G. Esplugues +5
Isotopic ratios have been used as chemical diagnostics to investigate the origin of the material in the Solar System. We have determined the HCN, HNC, and N2H+ isotopic ratios and…

The sulfur plume in the Horsehead nebula: New detections of SH, SH, and CO
Asunción Fuente, Gisela Esplugues, Pablo Rivière-Marichalar +13
Sulfur is essential for life, but its abundance and distribution in the interstellar medium remain uncertain, with over 90% of sulfur undetected in cold molecular clouds. Sulfur al…
