Externally Illuminated Young Stellar Environments in the Orion Nebula: [ITAL]Hubble[/ITAL] [ITAL]Space[/ITAL] [ITAL]Telescope[/ITAL] Planetary Camera and Ultraviolet Observations

Abstract

We present new resolution (22 AU) narrowband Hubble Space T elescope Planetary Camera 0A .05 images of externally illuminated young stellar objects embedded in the Orion Nebula. We also present resolution (9 AU) UV images of seven externally illuminated protostellar environments and the rst 0A .02 UV spectra that cover the spectral range between 1400 and 3000
