H2 bipolar emission associated with the quadrupolar molecular outflow in L723.
PALACIOS J. and EIROA C.
Abstract (from CDS):
We present near-infrared images of the quadrupolar CO outflow in L723, formed by two lobe pairs of different size. Bipolar molecular hydrogen line emission is detected, approximately centered on the Class 0 source L723 VLA2. One of the observed H2 nebulosities coincides with the Herbig-Haro object HH 223. The H2 bipolar outflow is projected against the large lobe pair of the quadrupolar CO outflow. Position angles of the H2 and HH emissions, large CO lobe pair and the thermal radio jet VLA2 are similar and also close to the magnetic field direction in the region. All these phenomena are likely powered by the young protostellar object L723 VLA2. Our near-infrared images do not show any near-ir counterpart of the smaller CO pair, whose origin and driving source remain unclear.
