NICMOS 2 MICRON CONTINUUM AND H-2 IMAGES OF OMC-1

The core of OMC-1 has been imaged with the Near-Infrared Camera and Mu ltiobject Spectrometer (NICMOS) on board the Hubble Space Telescope at 0''.2 resolution in 1% filters at 2.12 and 2.15 mu m, revealing intri cate structures in both continuum and shocked molecular hydrogen line emission. Numerous H-2-emitting clumps surrounding the BN/KL region ha ve been resolved for the first time, several of which exhibit prototyp ical bow-shock morphologies with V-shaped tips. We interpret these to be lower excitation analogs of similar structures similar to 2' northw est of the core observed with ground-based telescopes. Many of the elo ngated H-2 structures and bow-shock features appear to radiate outward from a region within a few arcseconds of radio source I, which sugges ts that the H-2 energetics are dominated by one or more outflow source s in this region. However, the orientations of some features are unrel ated to this apparent outflow pattern. The deeply embedded, suspected outflow source I remains undetected at 2 mu m, although two faint new continuum sources have been detected within similar to 1'' of it. The newly resolved H-2 features with bow-shock morphologies are located in regions previously identified as bow shocks by highly blueshifted com ponents in their line profiles. In contrast, regions of H-2 emission t hat are diffuse in the NICMOS image have broad, smooth line profiles. Several continuum features have an arclike appearance, which suggests interactions of winds with the ambient medium. At least 40 stellar or protostellar continuum sources have been detected, including at least one proplyd and four pairs of binary stars.
