Disk accretion powers many astronomical objects. Most interacting
binaries and many pre-main sequence stars contain rapidly-evolving
disks. More slowly-evolving, dusty disks orbit the Sun and β Pic.
A supermassive black hole surrounded by an enormous gaseous
disk lies at the center of every AGN or quasar. SSP scientists
use observations and theoretical models to learn how the central
stars and the disks evolve with time.
