Outward migration of planets due to Roche lobe overflow may play an important role in producing the presently observed distribution of planet parameters. We suggest that many of the currently known short period planets may have already migrated into the Roche distance from the star, and then deposited at their current semi-major axes by being migrated outwards due to angular momentum transfer from an episode of Roche lobe overflow (RLO). This RLO outward migration (RLOOM) could be sustained in the region where planetary radius increases with decreasing mass. We are modeling how RLOOM may leave what kind of planet parameter statistics. This modeling seeks to predict what observable signs of RLOOM there may be. Overflow of planetary mass may leave behind characteristic hot dust and gas as well as produce luminous signatures.
