H${}_2$ Emission Nebulosity Associated with KH 15D

Abstract

An H${}_2$ emission filament is found in close proximity to the unique object KH 15D using the adaptive optics system of the Subaru Telescope. The morphology of the filament, the presence of spectroscopic outflow signatures observed by Hamilton et al., and the detection of extended H${}_2$ emission from KH 15D by Deming, Charbonneau, & Harrington suggest that this filament arises from shocked H${}_2$ in an outflow. The filament extends about 15" to the north of KH 15D.
