Abstract

The sources L1551, IRC + 10216, and the Kleinmann-Low nebula possess microwave spectra indicative of mass-outflow at moderate to high velocities. In two of these cases the origin of outflow is probably to be located in newly formed or forming stars. For IRC + 10216 however it seems clear that the progenitor of the outflowing envelope is a late-type variable star. The current investigation is concerned with observations of these sources in the J = 3→2 transitions of CO and with photometry at wavelengths 377, 811, and 1136 micrometers. In L1551 the CO J = 1→0 and J = 2→1 lines show two components, a spike feature of width approximately 1.5 km/s, and a weaker but much broader 'wing' component. J = 3→2 CO spectra for three regions of this complex are shown.
