A Study of H2 Emission in Three Bipolar Proto-planetary Nebulae: Iras 16594−4656, Hen


We have carried out a spatial-kinematic study of three proto-planetary nebulae, IRAS 16594−4656, Hen 3-401, and Rob 22. High-resolution H2 images were obtained with NICMOS on the HST and high-resolution spectra were obtained with the Phoenix spectrograph on Gemini-South. IRAS 16594−4656 shows a “peanut-shaped” bipolar structure with H2 emission from the… (More)
