STAR FORMATION AND MOLECULAR CLOUDS

1. Resolve cloud fragments as small as 10 AU and detect fragments of only a few Jovian masses.

2. Identify regions of star formation in dark clouds with extensive spatial and kinematic mosaic images.

3. Image the chemical, density and velocity structure of proto-planetary disks.

4. Reveal the kinematics of the earliest phases of binary star formation.

5. Unveil the physical structure of circumstellar disks and determine their role in confining material outflow from protostars.

6. Determine the orientation and evolution of the magnetic field in circumstellar disks, from polarization observations of thermal dust emission.
