Interstellar deuteroammonia: Tracing physical conditions in dense, cold interstellar medium

Abstract

Close to 30 deuterated molecules have now been detected in the ISM, including doubly-deuterated species D_2H^+, ND_2H, D_2CO, CHD_2OH, D_2S, and D_2CS, as well as triply-deuterated ammonia and methanol. We review the current understanding of depletion and deuteration processes in cold, dense interstellar medium (ISM) and discuss the utility of deuteroammonia as a tracer of the physical conditions and kinematics of cold, dense gas.
