摘要：

We present near-infrared camera and Owens Valley millimeter interferometer data that reveal the circumstellar environment of TMR-1 (IRAS 04361 + 2547) on scales of roughly 1000 AU. TMR-1 is a deeply embedded, young, low-mass star located in a rotating ring of material in the TMC-1/Heiles Cloud 2 region of the Taurus molecular cloud. The stellar wind cavity, as outlined by the extended infrared continuum emission at 2.2 μm, overlaps with the redshifted outflow detected in the 12CO data. High-density circumstellar material is seen in 13CO in emission and at 2.2 μm in absorption. The morphology suggests the high-density gas may either be part of a ∼ 1000 AU disk or may represent infalling material from the molecular cloud core. TMR-1 appears to be in an early wind-clearing phase of protostar formation.
