Photoevaporation may provide an explanation for the short lifetimes of disks around young stars. With the exception of neutral oxygen lines, the observed low-velocit y forbidden line emission from T Tauri stars can b e reproduced b y photoevaporating models. The natural formation of a gap in the disk at several A U due to photoevaporation and viscous spreading provides a possible halting mechanism for migrating planets and an explanation for the abundance of observed planets at these radii.
