| Abstract: | We introduce a photogravitational version of Hill's problem to include the effect of radiation of the primaries, and discuss
its equilibrium points and zero velocity curves. As a first application we use this model to study Hill stability of orbits
around the small primary. The estimates obtained for the maximum distance of Hill stable orbits are compared to the predicted
maximum sizes of accretion disks in binary stars according to recent theories based on periodic orbits as streamlines of the
disks.
