H_2 EMISSION NEBULOSITY ASSOCIATED WITH KH 15D

摘要

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.
