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. MartÃn-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…
First Detection of CH3OD in Prestellar Cores
Beatrice M. Kulterer, Asunción Fuente, Maria N. Drozdovskaya +6
The isotopic ratios of deuterated methanol derived around protostars are commonly used to infer the physical conditions under which they formed in the earlier prestellar stage. How…
Photodesorption of SO2 and SO from UV-irradiated SO2 ices
Rafael MartÃn-Doménech, Bruno Escribano, David Navarro-Almaida +4
The detection of high gas-phase abundances of SO2 and SO in the cold envelope of an intermediate mass protostar suggests that these molecules might form on icy dust grains and subs…
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…
