The Last Gasps of a Dying Star: ALMA Observations of the Pre-Planetary Nebula IRAS 06530-0213
Raghvendra Sahai, Wouter Vlemmings, Guillermo Quintana-Lacaci +16
We present high angular-resolution () ALMA observations of millimeter-wave line and continuum emission (at and mm) in the pre-planetary ne…
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…
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-…
Rotating and Expanding Gas in Binary Post-AGB Stars
I. Gallardo Cava, V. Bujarrabal, J. Alcolea +4
There is a class of binary post-AGB stars (binary system including a post-AGB star) that are surrounded by Keplerian disks and outflows resulting from gas escaping from the disk. T…
Dissecting the central regions of OH 231.8 + 4.2 with ALMA: a salty rotating disk at the base of a young bipolar outflow
C. Sánchez Contreras, J. Alcolea, R. Rodríguez Cardoso +5
We present ALMA continuum and molecular line emission maps at 1 mm of OH 231.8, a well studied bipolar nebula around an AGB star. The excellent angular resolution of our maps…
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…
