Interpreting the 10um astronomical silicate feature
… 12 and towards field and embedded objects in the Taurus Molecular Cloud (TMC) were obtained with CGS3 at the United Kingdom Infrared Telescope (UKIRT). Cold molecular-cloud silicates are sampled in quiescent lines of sight towards the field stars Taurus-Elias 16 and Elias 13, whilst observations …

Circumstellar Structure Properties of Young Stellar Objects: Envelopes, Bipolar Outflows, and Disks
… disks: We present the results of 6 objects (CI Tau, DL Tau, DO Tau, FT Tau, Haro 6-13, and HL Tau) in our T Tauri disk survey using CARMA. The data consist of 1.3 mm and 2.7 mm continuum with an angular resolution up to 0.13′′. Through visibility modeling of two disk models (power-law disk with …

Astronomical Interferometry at Submillimetre Wavelengths
… of our galaxy, and the nearby radio-galaxy Centaurus A. This is followed by a more detailed analysis of data for the evolved star VY CMa and observations of discs around young stars. Spectra of the 321 GHz H20 line from VY CMa confirm that maser amplification is responsible for the emission. …

Observations of disks around the youngest protostars: Characterizing frequency, dust properties, and magnetic fields at the earliest times
… disks of more evolved Class II sources such as HL Tau. Since rings and gaps are observed in IRS 63, then planet formation or other associated disk sculpting must have started early in the Class I phase or before.
