Title: NGC 2346 and NGC 40 Imaged in Molecular Hydrogen

Abstract: Planetary nebulae (PNe) and the small scale structures (eg. cometary knots) within are pivotal in our understanding of the redistribution of material into the interstellar medium (ISM). Small scale structures in planetary nebulae (PNe) are known to be an important contributor to our understanding of the role of gas and dust in the evolution of the nebula and beyond, specifically in the shielding of molecular material (eg. molecular hydrogen) which should ordinarily be unable to survive the harsh UV environment inherent to PNe. We request the use of WHIRC+WTTM on WIYN in order to obtain narrow band images of hydrogen (Br $\gamma$) and molecular hydrogen (H$_2$) of the planetary nebulae, NGC 2346 and NGC 40. These images will be used to determine the extent and spatial distribution (eg. knots) of molecular gas within the PNe as it pertains to the formation and survival of molecular material to the ISM.
