MUSE imaging spectroscopy of the fullerene planetary nebula Tc 1
Astronomy & AstrophysicsAims. The planetary nebula Tc 1 (PN G345.2–08.8), one of the rare group of Galactic PNe showing fullerene emission in the infrared, is spatially extended with high a surface brightness.

Whither or Wither the Sulfur Anomaly in Planetary Nebulae?
The Astrophysical Journal LettersWe present a thorough investigation of the long-standing sulfur anomaly enigma. Our analysis uses chemical abundances from the most extensive data set available for 126 planetary nebulae (PNs) with improved accuracy and reduced uncertainties from a 10° ×

Close Binaries and the Abundance Discrepancy Problem in Planetary Nebulae
Galaxies, 2018 Motivated by the recent establishment of a connection between central star binarity and extreme abundance discrepancies in planetary nebulae, we have carried out a spectroscopic survey targeting planetary nebula with binary central stars and previously ...

A new [OIII] lambda5007 Å Galactic Planetary Nebulae Luminosity Function
, 2010 The Planetary Nebulae Luminosity Function (PNLF) describes the collective luminosity evolution for a given population of Planetary Nebulae (PN). A major paradox in current PNLF studies is in the universality of the absolute magnitude of the brightest PNe

The temperature structure of dusty planetary nebulae
, 2001 We have analyzed the effects of photoelectric heating by dust grains in photoionization models of planetary nebulae. We have shown that this process is particularly important if planetary nebulae contain a population of small grains. The presence of such
