Scientific paper

With NICMOS/NIC2 imaging of five brown dwarfs and one low mass star that we have identfied in a young cluster in OMC2/3, we plan to assess the similarities between brown dwarf formation and low mass star formation by searching for the presence of shocked H2 line emission from jets/outflows, close binary companions, and/or reflection nebulosity from protostellar envelopes and outflow cavities. The detection of these phenomena would be evidence that brown dwarfs result from the continuation of the the star formation process to masses below the hydrogen burning limit, and not through the dynamical ejection of stellar embryos as has been recently proposed. This proposal is complmentary to our SIRTF GTO program designed to search for circumstellar disks by measuring the spectral energy distribution of these sources out to 8 microns. This task requires not only high spatial resolution, but also a stable, unchanging PSF such as HST provides.
