| Abstract: |
Bipolar outflows from young stellar objects are excellent
laboratories to study shock chemistry in the interstellar medium.
Observations show that a number of molecular species suffer
order-of-magnitude abundance enhancements in the outflow gas, likely
due to a combination of dust-mantle disruption and high-temperature
gas chemistry. The study of these enhanced species is of great interest
to characterize shock chemistry. It also offers a highly selective tool
to trace the interaction between the outflow and the cloud, which is
necessary to elucidate the still mysterious nature of the outflow driving
wind. This contribution reviews some of the recent progress in the study
of the molecular composition of bipolar outflows with emphasis on the tracers
most relevant for shock chemistry and on the new data from the Herschel
Space Observatory. |
