HH 114 MMS: a new chemically active outflow.

TAFALLA M. and HACAR A.

Abstract (from CDS):

A small group of bipolar protostellar outflows display strong emission from shock-tracer molecules such as SiO and CH3OH, and are generally referred to as ``chemically active''. The best-studied outflow from this group is the one in L 1157. We study the molecular emission from the bipolar outflow powered by the very young stellar object HH 114 MMS and compare its chemical composition with that of the L 1157 outflow. We have used the IRAM 30 m radio telescope to observe a number of transitions from CO, SiO, CH3OH, SO, CS, HCN, and HCO+ toward the HH 114 MMS outflow. The observations consist of maps and a two-position molecular survey. The HH 114 MMS outflow presents strong emission from a number of shock-tracer molecules that dominate the appearance of the maps around the central source. The abundance of these molecules is comparable to the abundance in L 1157. The outflow from HH 114 MMS is a spectacular new case of a chemically active outflow.
