  IRAS04325+2402C is a low luminosity object located near a protostar in
Taurus. We present new spatially-resolved mm observations, near-infrared
spectroscopy, and Spitzer photometry that improve the constraints on the nature
of this source. The object is clearly detected in our 1.3 mm interferometry
map, allowing us to estimate the mass in a localized disk+envelope around it to
be in the range of 0.001 to 0.01Ms. Thus IRAS04325C is unlikely to accrete
significantly more mass. The near-infrared spectrum cannot be explained with an
extincted photosphere alone, but is consistent with a 0.03-0.1Ms central source
plus moderate veiling, seen in scattered light, confirming the edge-on nature
of the disk. Based on K-band flux and spectral slope we conclude that a central
object mass >~0.1Ms is unlikely. Our comparison of the full spectral energy
distribution, including new Spitzer photometry, with radiative transfer models
confirms the high inclination of the disk (>~80deg), the very low mass of the
central source, and the small amount of circumstellar material. IRAS04325C is
one of the lowest mass objects with a resolved edge-on disk known to date,
possibly a young brown dwarf, and a likely wide companion to a more massive
star. With these combined properties, it represents a unique case to study the
formation and early evolution of very low mass objects.
