Externally Illuminated Proto-Planetary Disks

We used the Hubble Space Telescope (HST) to obtain high angular resolution images and the first UV spectra of young stars and their circumstellar environments embedded within the Orion Nebula. The observations consists of: Direct imaging of young stars, their disks, and the surrounding environments with the Planetary Camera (PC) portion of Wide Field and Planetary Camera (WFPC2) using narrow band interference filters; The first UV imaging of these objects with the Faint Object Camera (FOC); and The first UV spectroscopy of these objects using the Faint Object Spectrograph (FOS).
