An Infrared Study of the Juggler NebulaThis work is an examination of the infrared reflection nebula surrounding a protostellar source, IRS 1, in the CRL 2136 region at 2.2, 3.08, and 3.45 micron. The greatest absorption due to water ice occurs within 5 arcsec (10,000 AU, D = 2000 pc) of IRS 1. The water ice absorption decreases with increasing radius from IRS 1. This Tau(sub ice) structure suggests that the water ice is primarily associated with IRS 1. The flux from IRS 1 has a (2.2) - (3.45) color of 5, much redder than the nebula. The color structure combined with the Tau(sub ice) structure suggests the presence of an icy-dusty disk around IRS 1 orientated NE to SW. Radio CO maps presented by Kastner et al. reveal a molecular outflow orientated perpendicular to the disk. The south and east reflection lobes line the conical cavity created by the blueshifted molecular outflow.
