Scientific paper

Under the assumption that the closure density of the universe is provided by low-mass stars below the hydrogen burning limit (i.e., 'Jupiters'), the contribution of these objects to the electromagnetic background is calculated. The resultant spectrum is found to deviate significantly from a blackbody spectrum, thus providing a distinctive radiation signature. The peak of the spectrum is broad and depends only weakly on mass, and is found to lie between lambda = 10-100 microns for the mass ranges considered. For certain cases the peak brightness is found to approach 10,000 Jy/sr. This is about one order of magnitude below the detection limit of present day instruments.
