Title: Imaging molecular hydrogen in the outer regions of NGC 6853

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 on WIYN in order to obtain narrow band images of molecular hydrogen (H$_2$) in the outer portions of the planetary nebulae, NGC 6853 (Dumbbell Nebula). These images will be used to determine the extent and spatial distribution of molecular gas within the outer regions of the PN as it pertains to the formation and survival of molecular material to the ISM.

Program Type: MOTAC

Scheduled Nights:
Run 1 (2017A):  WIYN/WHIRC -- 3.5n on May 15 - May 20 2017
