Probing the Molecular Hearts of Extreme Bipolar Planetary Nebulae with ALMA
Paula Moraga Baez, Joel H. Kastner, Jesse Bublitz +6
We present results from a program of Atacama Large Millimeter Array (ALMA) 1.3 mm (Band 6) molecular line mapping of a sample of nearby, bipolar/pinched-waist, molecule-rich PNe (N…
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…
The Molecular Exoskeleton of the Ring-like Planetary Nebula NGC 3132
Joel H. Kastner, David Wilner, Paula Moraga Baez +4
We present Submillimeter Array (SMA) mapping of CO , CO , and CN emission from the Ring-like planetary nebula (…
The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
Orsola De Marco, Muhammad Akashi, Stavros Akras +66
Planetary nebulae (PNe), the ejected envelopes of red giant stars, provide us with a history of the last, mass-losing phases of 90 percent of stars initially more massive than the…
Panchromatic HST/WFC3 Imaging Studies of Young, Rapidly Evolving Planetary Nebulae. II. NGC 7027
Paula Moraga Baez, Joel H. Kastner, Bruce Balick +2
The iconic planetary nebula (PN) NGC 7027 is bright, nearby (D ~ 1 kpc), highly ionized, intricately structured, and well observed. This nebula is hence an ideal case study for und…
Mapping NGC 7027 in New Light: CO and HCO Emission Reveal Its Photon- and X-ray-Dominated Regions
Jesse Bublitz, Joel H. Kastner, Pierre Hily-Blant +7
The young and well-studied planetary nebula NGC 7027 harbors significant molecular gas that is irradiated by luminous, point-like UV (central star) and diffuse (shocked nebular) X-…
Sampling Molecular Gas in the Helix Planetary Nebula: Variation in HNC/HCN with UV Flux
Jesse Bublitz, Joel H. Kastner, Pierre Hily-Blant +4
Observations of molecular clouds, prestellar cores, and protoplanetary disks have established that the HNC/HCN ratio may be a potent diagnostic of molecular gas physical conditions…
A twin-jet structure rather than jet-rotation in the young stellar object OMC 2/FIR 6b
Noam Soker, Jesse Bublitz, Joel H. Kastner
We analyse recent high-quality Atacama Large Millimeter Array (ALMA) molecular line mapping observations of the northeast jet of the young stellar object (YSO) OMC 2/FIR6b (HOPS-60…
Panchromatic HST/WFC3 Imaging Studies of Young, Rapidly Evolving Planetary Nebulae. I. NGC 6302
Joel H. Kastner, Paula Moraga, Bruce Balick +4
We present the results of a comprehensive, near-UV-to-near-IR Hubble Space Telescope WFC3 imaging study of the young planetary nebula (PN) NGC 6302, the archetype of the class of e…
A New Radio Molecular Line Survey of Planetary Nebulae: HNC/HCN as a Diagnostic of Ultraviolet Irradiation
Jesse Bublitz, Joel H. Kastner, Miguel Santander-García +3
Certain planetary nebulae contain shells, filaments, or globules of cold gas and dust whose heating and chemistry are likely driven by UV and X-ray emission from their central star…
