Scientific paper

K-band images around GL 490 and R Mon are presented. Both maps show that a curved ridge encloses a dim region in an infrared reflection nebula. This ridge is created by scattering from a dense shell of material and can be directly observed in the near-infrared because the optical depth is small. R Mon also shows an extension perpendicular to that of the infrared reflection nebula. It is believed that this feature arises from scattering by dust in the disk because of the spatial coincidence with the molecular disk. The column densities in the shell around R Mon calculated using a dust model derived for interstellar dust are about an order of magnitude larger than that expected from radio molecular line observations. This discrepancy can be resolved if we assume large dust grains in this star-forming region.
