"What can UV/optical/and near-IR variability tell us about accretion onto
stars and black holes"

Accretion is one of the most important but least understood physical processes
in the Universe. On the largest scales, after fusion in stars, it provides the
biggest source of energy in the history of the Universe. On smaller scales, it
is the process by which stars and planets form. Yet as important as accretion
is, it happens on scales that are not resolvable with any current, or planned
future, telescope. But accretion is a variable process, so we can trade time
resolution for spatial resolution to discern the structure of everything from
planet forming disks around nearby stars to accretion disks around distant
black holes.
