Scientific paper

We will obtain low resolution {G230L} spectroscopy of select proplyds located near the Trapezium cluster in Orion. These observations will determine the NUV emission from the ionization fronts, circumstellar disks, "tails", and extended arcs of emission associated with these proplyds and will be used to investigate current photoionization and wind-wind interaction models of proplyds. The slit orientations have been chosen to include a "microjet" and several HH objects associated with one of the proplyds. These observations will also identify possible targets for future high resolution observations of the CIII]{1909} emission from the proplyds which can be used to determine mass loss rates and expected lifetimes for circumstellar disks located near O stars.
