Abstract: Disk holes are inferred from infrared observations of T Tauri stars, indicating the existence of a transitional phase between thick accreting disks and debris disks. Using data from the observational multiwavelength campaign CSI2264, we analyzed 410 stars belonging to NGC 2264 and found about 7% transition disk candidates. We characterized these star-disk systems using accretion diagnostics and we compared them with star-disk systems with full disks and diskless. We were able to evaluate the influence of disk evolution on the observed accretion characteristics.
