Just got word of this one...  Sorry for the late notice!

>Abstract: Over the past 10 years abundant evidence has emerged that many
>(if not all) stars are born with circumstellar disks. Understanding the
>evolution of disks can provide strong constraints on theories of planet
>formation. In addition, characterizing the physical properties of disks
>can provide valuable insight into the star formation process. While
>concensus is emerging concerning the the early evolution of accretion
>disks (tau < 10 Myr) and the characterization of older debris disks (tau >
>1 Gyr) continues at a rapid pace little is known about the transition
>between these two extremes thought to occur during the epoch of planet
>formation. Recent studies undertaken with ground and space-based
>observatories are helping to address questions concerning the structure
>and evolution of disks around young stars. New results from these programs
>will be presented and directions for future research will be discussed. In
>particular, the promise of NASA's Space Infrared Telescope Facility,
>launched in August, 2003, to help us understand the formation and
>evolution of planetary systems will be summarized.
