Scientific paper

Determining the timescales for gas accretion and dust growth and settling requires samples of objects at ages 1 to 50 Myr. We present evidence of dust evolution in Orion OB1 disks, spanning the age range ~4-10 Myr. Our results support the notion of two characteristic timescales for disk dissipation: the mean disk lifetime and the time for the transition from optically thick to optically thin or no inner disk. We also find clear evidence of accretion even at 10Myr. The IRAC photometry reveals a population of transition objects with signatures of inner disk clearing. Our results suggest a short (< 1 Myr) timescale for the dissipation of the inner few AU in protoplanetary disks, and a rapid stopping of disk accretion in this transition phase.
