    "description": "<p>&nbsp;</p>\n\n<p>External UV environment of stellar nurseries plays a major role on evolution of protoplanetary disks around young stellar objects.&nbsp; Photoevaporating protoplanetary disks (proplyds) have been found mainly around O stars in strong radiation environments, most of which are found in the Orion Nebula Cluster.&nbsp; However our recent studies also found proplyds in immediate vicinity of B stars, which implies that intermediate UV radiation environment can also affect disk evolution of young stellar objects, and&nbsp; potentially planet formation in such disks.&nbsp; We present our recent studies of proplyds around low mass young stellar- and sub-stellar objects, some of which may be potentially forming free-floating planetary mass objects. &nbsp; We will present our findings of the proplyds in NGC 1977 and NGC 2024, and show some selected proplyds around low mass sub-stellar objects. We will discuss the implication and the role of external UV environment in star and planet formation.&nbsp;</p>",
