[20.13] Near-infrared Survey of Molecular Cloud L1630

W. Li, N. J. Evans II (U. Texas), E. A. Lada (U. Maryland)

A near-infrared survey covering about 2000 square arcminutes of the molecular cloud L1630 has been conducted using the KPNO SQIID on the 50-inch telescope. The study has concentrated on the regions away from the infrared clusters, where star formation is extremely active. The goal of the survey is to search for evidence of star formation in the cloud peripheral areas, where the column density and visual extinction are modest (A_V \sim 4-8). Combined with the information obtained from molecular tracers and tracers of photon-dominated regions, we hope to test the model of photoionization-regulated star formation proposed by McKee (1989). Initial results of the near-infrared survey will be presented at the meeting.
