Shock waves in young molecular outflows disrupt the ice mantles and allow us to directly probe the material that is ejected into the gas phase. A comprehensive study of sulfur-bearing species toward L1157-B1, a shocked region along a protostellar outflow, has been carried out as part of the IRAM-30 m large program ASAI. The data set contains over 100 lines of CCS, H<SUB>2</SUB>CS, OCS, SO, SO<SUB>2</SUB>, and isotopologues. The results of these observations are presented, complementing previous studies of sulfur-bearing species in the region. The column densities and fractional abundances of these species are measured and together these species account for 10% of the cosmic sulfur abundance in the region. The gas properties derived from the observations are also presented, demonstrating that sulfur bearing species trace a wide range of different gas conditions in the region.STAMPAenArticle10.3847/1538-4357/ab1cb52-s2.0-85069448073000471729200002https://iopscience.iop.org/article/10.3847/1538-4357/ab1cb5/pdf2019ApJ...878...64HFIS/05 - ASTRONOMIA E ASTROFISICA
