The evolving spectrum of the planetary nebula Hen 2-260

, 2014
We analysed the planetary nebula Hen 2-260 using optical spectroscopy and photometry. We compared our observations with the data from literature to search for evolutionary changes.

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.

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 ...

Photo-ionization modelling of planetary nebulae -- II. Galactic bulge nebulae, a comparison with literature results

, 1999
We have constructed photo-ionization models of five galactic bulge planetary nebulae using our automatic method which enables a fully self-consistent determination of the physical parameters of a planetary nebula.
