Thompson, R. I. ; Tokunaga, A. T. Abstract Upper limits have been placed on the B-gamma flux from three objects (S140 IR, Mon R2 IRS 3, and R Mon). In each case these observations result in upper limits on the Ne-squared V value for the object and on the spectral type of the zero-age main-sequence star that may be contained in the object. These limits appear consistent with the total luminosity of the objects. Upper limits are also placed on the molecular hydrogen emission from the objects.
