摘要：

The environs of the pre-main-sequence, emission-line star, LkHα 101, have been observed by broad-band CCD imaging, high-resolution (Δυ = 25 km s-1) optical spectroscopy, IRAS imaging, and single-dish, as well as interferometric, millimeter-line mapping. LkHα 101 exhibits a high mass-loss rate (1.1 × 10-5) low-velocity (350 km s-1) ionized wind typical of early-type pre-main-sequence stars (Barsony 1989). The millimeter interferometer maps show that this wind has cleared out a cavity in the molecular cloud surrounding LkHα 101, allowing the rapid expansion of the previously observed VLA H II region (Becker and White 1988).
