ALMA Observations of Molecular Line Emission from High-excitation Bipolar Planetary Nebulae
Paula Moraga Baez, Joel H. Kastner, Jesse Bublitz +7
We present early results from our program of ALMA Band 6 (1.3mm) molecular line mapping of a sample of nearby, well-studied examples of high-excitation, bipolar/pinched-waist and m…
