HCN/HNC chemistry in shocks: a study of L1157-B1 with ASAI
B. Lefloch, G. Busquet, S. Viti +9
HCN and its isomer HNC play an important role in molecular cloud chemistry and the formation of more complex molecules. We investigate here the impact of protostellar shocks on the…
Water in star-forming regions (WISH): Physics and chemistry from clouds to disks as probed by Herschel spectroscopy
E. F. van Dishoeck, L. E. Kristensen, the WISH team
(abridged) Data and results from the WISH key program are summarized, designed to provide a legacy data set to address its physics and chemistry. WISH targeted ~80 sources along th…
Seed of Life in Space (SOLIS) XI. First measurement of nitrogen fractionation in shocked clumps of the L1157 protostellar outflow
M. Benedettini, S. Viti, C. Codella +11
The isotopic ratio of nitrogen presents a wide range of values in the Solar System and in star forming system whose origin is still unclear. Chemical reactions in the gas phase are…
Sulfur Chemistry in L1157-B1
Jonathan Holdship, Izaskun Jimenez-Serra, Serena Viti +7
The main carrier of sulfur in dense clouds, where it is depleted from the gas phase, remains a mystery. Shock waves in young molecular outflows disrupt the ice mantles and allow us…
A search for Cyanopolyynes in L1157-B1
E. Mendoza, B. Lefloch, C. Ceccarelli +10
We present here a systematic search for cyanopolyynes in the shock region L1157-B1 and its associated protostar L1157-mm in the framework of the Large Program "Astrochemical Survey…
The L1157-B1 astrochemical laboratory: testing the origin of DCN
G. Busquet, F. Fontani, S. Viti +4
L1157-B1 is the brightest shocked region of the large-scale molecular outflow, considered the prototype of chemically rich outflows, being the ideal laboratory to study how shocks…
