[89.03] Circumstellar Disk Candidates Identified in NGC~2264

Based on an optical and near-infrared study of a 45\arcmin\times45\arcmin field in NGC 2264, which includes both S Mon and the Cone Nebula, we identify circumstellar disk candidates using three techniques: excess ultraviolet (U-V) emission, excess near-IR (I-K and H-K) emission, and H\alpha emission line equivalent widths. We find generally good correlation between disk indicators thought to originate from different physical processes. We find little if any evolution of disk fraction with stellar age or mass.
