photoevaporation

(dispersal of a gas from UV radiation)

Photoevaporation is the dispersal of a gas from the energy of XEUV radiation. (Thus it is not "evaporation" in the sense of a liquid changing to a gas.) The term photoevaporation is used for molecular clouds, protoplanetary disks, and the atmosphere of planets (atmospheric escape). Due to this process, extra-solar planets close enough to stars emitting significant ultraviolet radiation are expected to have had their atmosphere stripped away.
