Abstract
We report high spatial (0.5") and high spectral (9 km s-1) resolution spectro-imaging of the 2.12 μm H2 1-->0 S(1) line in the proto-planetary nebula AFGL 618 using BEAR at the Canada-France-Hawaii Telescope. The observations reveal the presence of multiple, high-velocity, molecular outflows that align with the remarkable optical jets seen in Hubble Space Telescope images. The structure and kinematics of the outflows show how jets interact with circumstellar gas and shape the environment in which planetary nebulae form.
Based on observations collected at the Canada-France-Hawaii Telescope, operated by the National Research Council of Canada, the Centre National de la Recherche Scientifique de France, and the University of Hawaii.
