Low-Luminosity embedded sources and their environs

A far-infrared and submillimeter study of regions within 0.03 pc of the low-luminosity sources embedded in the clouds B335, L723, B361, L1455, and L1551 is presented along with CO molecular line results on the extended environments of these sources out to 0.3 pc. Three of the embedded objects are definite bipolar outflow sources, one may be associated with an observed outflow, and one has no observable outflow. Data on the outflows are combined with determination of the luminosity of the embedded objects, and of the temperature and matter distribution about the sources, to infer the evolutionary stage of the embedded sources.
