Circumstellar Envelopes and Disks of Pre-Main Sequence Starsccrete substantial amounts of mass may be seen through their dusty infalling envelopes even at optical wavelengths, because of the presence of holes or large departures from spherical symmetry in the envelopes. The evidence for this picture is summarized in the context of one well-studied young star

Observations of Disks around Protostellar Sources with Nobeyama Millimeter Array shows that the 98 GHz continuum emission tends to be weaker for embedded sources than for visible T Tauri stars, which is consistent with our previous interpretation of disk formation. Direct observations of the formation of a centrifugally supported viscous accretion disk around HL Tau is discusse

Near-IR Spectroscopy and the Photospheres of Embedded YSOsrtone absorption bands of varying strength in the K window, whether they have optical counterparts or not. Class I sources tend to show featureless 2 . continua even though a S/N > 100 was achieved. High resolution (R=17000) echelle spectra were also obtained for a sub-sample of YSOs. Most show an u

Millimeter Polarimetry of Star-Forming Regions: Magnetic Field Structure around Low-Mass Starsor NGC 1333 IRAS 4 and IRAS 16293-2422, while L1551 IRS5 and HL Tau were only marginally detected. For GG Tau we measured a 2 . upper limit of 3%. The polarization is interpreted in terms of thermal emission by magnetically aligned dust grains in circumstellar disks or envelopes. We have found a def

Infrared CO Emission and Disks around Young Starstellar disks around young stars. The CO emission flux and the detailed shape of the overtone bands are well matched by simple Keplerian disk models. A brief overview of the use of infrared CO emission as a diagnostic of the kinematics and conditions of gas in the inner disks of young stars is presen
