The San Pedro M��rtir Planetary Nebula Kinematic Catalogue: Extragalactic Planetary Nebulae
, 2010 We present kinematic data for 211 bright planetary nebulae in eleven Local Group galaxies: M31 (137 PNe), M32 (13), M33 (33), Fornax (1), Sagittarius (3), NGC 147 (2), NGC 185 (5), NGC 205 (9), NGC 6822 (5), Leo A (1), and Sextans A (1). The data were acquired at the Observatorio Astron mico Nacional in the Sierra de San Pedro M rtir using the 2.1m ...

The Secular Evolution of Planetary Nebula IC 418 and Its Implications for Carbon Star Formation
The Astrophysical Journal LettersThe rate of stellar evolution can rarely be measured in real time. The fastest evolution (excluding event-driven evolution), where stars may evolve measurably over decades, is during the post–Asymptotic Giant Branch (AGB) phase. In this Letter we provide

A study of four multipolar planetary nebulae in the Galactic bulge
Astronomy & AstrophysicsWe present infrared (IR) spectroscopic and optical morphological analyses of four multipolar young planetary nebulae (PNe) located in the Galactic bulge (GB) to investigate their dust characteristics and complex multi-lobed structures.

Spectroscopic Survey of Faint Planetary-nebula Nuclei. IV. The A35-type Central Star of Pa 27
The Astrophysical JournalWe present optical spectroscopy of the 12th-magnitude central star of the planetary nebula (PN) Patchick 27 (Pa 27), obtained during a survey of faint PN nuclei (PNNs) with the Low-Resolution Spectrograph of the Hobby–Eberly Telescope.

Planetary Nebulae in the eROSITA eRASS1 Catalog
The Astrophysical JournalSome planetary nebulae (PNs) host X-ray-emitting hot bubbles shaped by stellar wind interactions and/or harbor X-ray-emitting central stars due to accretion, shocks within their fast stellar winds, or even chromospheric emission from binary companions ...
