A GLOBAL-MODEL OF PROTOSTELLAR BIPOLAR OUTFLOW .2.

This paper presents synthetic (CO)-C-13 J=1-->0 line profiles, radio m aps of total red and blueshifted intensity, and channel maps computed for the virial-isothermal and radiation-dominated bipolar outflow mode ls presented in Paper I of this series. This imaging technique allows us to directly compare our model with radio maps of real outflow sourc es. We find that our line profiles are similar to real profiles in bot h amplitude and shape. In particular, high-velocity wing emission is c learly found in the outflow region. Maps of total integrated red and b lueshifted intensity are found to be dominated by the low-velocity cir culation component of our solution, which comprises the bulk of the ma terial. Velocity-resolved channel mapping reveals the detailed radio s tructure of the outflow and jet regions. These images clearly demonstr ate the velocity dependence of the outflow opening angle as described in Paper I; collimation of the radio jet increases with velocity. We a lso show that the radio jet appears to be accelerating away from the p rotostar at some inclination angles. This is a projection effect which we explain by the structure of the jet region and the mapping geometr y. At high inclination angles, our channel maps reveal a well-defined rotating torus surrounding the protostar. Confusion effects are examin ed by computing line profiles and maps both for solutions in vacuo and for solutions that are smoothly merged with an extended spherical reg ion of constant density and temperature.
