Abstract

Observations of dust and gas-phase molecules are compared as probes of the embedded phase of low-mass star formation. Results are presented of a detailed study of a sample of low-mass young stellar objects in Taurus with single-dish and interferometer millimeter observations. At least 67% of the objects have compact circumstellar disks, in addition to extended envelopes. HCO+ is found to be an excellent tracer of envelope structure. Interferometer observations of its 1–0 line, and of 13CO and C18O, reveal the kinematics of the equatorial regions of the envelopes, and the interaction with the bipolar outflows.
