The enigmatic central star of the planetary nebula PRTM 1

, 2012
The central star of the planetary nebula PRTM 1 (PN G243.8-37.1) was previously found to be variable by M. Pena and colleagues. As part of a larger programme aimed towards finding post common-envelope binary central stars we have monitored the central ...

Tycho Supernova Exploded Inside a Planetary Nebula (SNIP)

Universe
I analyze recent X-ray data from the literature of the type Ia supernova remnant (SNR Ia) Tycho and conclude that Tycho is a SN Ia inside a planetary nebula (SNIP), strengthening such a previous suggestion from 1985.

The Molecular Exoskeleton of the Ring-like Planetary Nebula NGC 3132

The Astrophysical Journal
We present Submillimeter Array (SMA) mapping of ^12 CO J = 2 → 1, ^13 CO J = 2 → 1, and CN N = 2 → 1 emission from the ring-like planetary nebula NGC 3132, one of the subjects of JWST Early Release Observation near-infrared imaging.

G313.3+00.3: A New Planetary Nebula discovered by the Australia Telescope Compact Array and the Spitzer Space Telescope

, 2005
We present a new planetary nebula, first identified in images from the Australia Telescope Compact Array, although not recognized at that time. Recent observations with the Spitzer Space Telescope during the GLIMPSE Legacy program have rediscovered the ...

Radiation Transfer in the Cavity and Shell of Planetary Nebulae

, 2012
We develop an approximate analytical solution for the transfer of line-averaged radiation in the hydrogen recombination lines for the ionized cavity and molecular shell of a spherically symmetric planetary nebula.

The kinematics of the most oxygen-poor planetary nebula PN G135.9+55.9

, 2003
PN G135.9+55.9 is a compact, high excitation nebula that has been identified recently as the most oxygen-poor halo planetary nebula. Given its very peculiar characteristics and potential implications in the realms of stellar and Galactic evolution ...
