Water enhances the formation of refractory sulfur in interstellar ices

Carlos del Burgo Olivares, Hector Carrascosa, Guillermo M. Muñoz Caro +3

Sulfur is the tenth most abundant element in space, yet it is strongly depleted in the gas phase of dense interstellar regions, suggesting sequestration in dust grain components th…

Modeling the UV-photon irradiation of CS-bearing ices in the laboratory with the pyRate gas-grain astrochemical code. New insights into the missing sulfur problem

O. Sipilä, R. Martín-Doménech, W. Riedel +4

Observations indicate that the total abundance of S-bearing species in dense clouds is orders of magnitude lower than the cosmic sulfur abundance. Addressing this "missing sulfur p…

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…
