Observations of dust and molecules in the disks and envelopes of young stellar objects

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 ^(13)CO and C^(18)O, reveal the kinematics of the equatorial regions of the envelopes, and the interaction with the bipolar outflows.
