[79.01] Distribution of Young Stars in the Rosette Molecular Cloud: Results from a JHK Survey

We present the results of a near-infrared imaging survey of the Rosette Molecular Cloud. The data were taken the NOAO Simultaneous Quad Infrared Imaging Device (SQIID) on the 1.3 meter telescope at the Kitt Peak National Observatory. We observed 155 fields at J, H, and K bands imaging an area of approximately 0.7 square degrees and covering most of the 13CO emission from the cloud (Blitz & Stark 1987). We have completed J, H, K photometry and astrometry for each of our observed fields. We investigate the distribution of young sources in the cloud to determine whether the stars in our magnitude limited sample are preferentially found inside or outside of embedded clusters. In addition, we present a JHK color-color analysis of all sources to study the frequency and spatial distributions of young sources exhibiting near-infrared emission from circumstellar disks.
