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…
NGC 6302: The Tempestuous Life of a Butterfly
Bruce Balick, Lars Borchert, Joel H. Kastner +4
NGC 6302 (The ''Butterfly Nebula'') is an extremely energetic bipolar nebula whose central star is among the most massive, hottest, and presumably rapidly evolving of all central s…
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…
Excitation & Excavation of the Claws of the Southern Crab
Bruce Balick, Ashley Swegel, Adam Frank
We show that the Southern Crab (aka Hen2-104) presents an auspicious opportunity to study the form and speed of the invisible winds that excavate and shock the lobes of various typ…
On the most luminous planetary nebulae of M31
Rebeca Galera-Rosillo, Antonio Mampaso, Romano L. M. Corradi +6
To study the progenitors of PNe at the tip of the Planetary Nebula Luminosity Function (PNLF), we obtained the deepest existing spectra of a sample of PNe in the galaxy M31. Precis…
