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…

ALMA detection of Masers and Dasars in the Hydrogen Recombination Lines of the Planetary Nebula Mz3

Z. Abraham, P. P. B. Beaklini, I. Aleman +5

The hydrogen recombination lines H30, H40, H42, H50 and H57 and the underlying bremsstrahlung continuum emission were detected with ALMA in the bipolar nebula Mz3. T…

High-Speed Outflows and Dusty Disks during the AGB to PN Transition: The PANORAMA survey

Raghvendra Sahai, Javier Alcolea, Bruce Balick +15

As mass-losing asymptotic giant branch (AGB) stars evolve to planetary nebulae (PNe), the mass outflow geometries transform from nearly spherical to extreme aspherical. The physica…

Seimei KOOLS-IFU mapping of the gas and dust distributions in Galactic PNe: Unveiling the origin and evolution of Galactic halo PN H4-1

Masaaki Otsuka, Toshiya Ueta, Akito Tajitsu

H4-1 is a planetary nebula (PN) located in the Galactic halo, and is notably carbon-rich and one of the most metal-deficient PNe in the Milky Way. To unveil its progenitor evolutio…

The porous envelope and circumstellar wind matter of the closest carbon star, CW Leonis

Hyosun Kim, Ho-Gyu Lee, Youichi Ohyama +5

Recent abrupt changes of CW Leonis may indicate that we are witnessing the moment that the central carbon star is evolving off the Asymptotic Giant Branch (AGB) and entering into t…

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…
