Binary Central Stars of Planetary Nebulae
Galaxies, 2020 It is now clear that a vast majority of intermediate-mass stars have stellar and/or sub-stellar companions, therefore it is no longer appropriate to consider planetary nebulae as a single-star phenomenon, although some single, isolated stars may well ...

The Formation of Fullerenes in Planetary Nebulae [PDF]
Galaxies, 2018 In the last decade, fullerenes have been detected in a variety of astrophysical environments, with the majority being found in planetary nebulae. Laboratory experiments have provided us with insights into the conditions and pathways that can lead to ...

Galaxies, 2018 The increase in discovered close binary central stars of planetary nebulae is leading to a sufficiently large sample to begin to make broader conclusions about the effect of close binary stars on common envelope evolution and planetary nebula formation ...

Lessons from the Ionised and Molecular Mass of Post-CE PNe
Galaxies, 2022 Close binary evolution is widely invoked to explain the formation of axisymmetric planetary nebulae after a brief common envelope phase. The evolution of the primary would be interrupted abruptly, its still quite massive envelope being fully ejected to ...

Shaping of Planetary Nebulae by Exoplanets
Galaxies, 2020 (1) Background: We investigate the hypothesis that exoplanet engulfment can help explain the observed non-spherical planetary nebula population, as a complementary shaping mechanism to the binary hypothesis.

Observing the signatures of AGB s-process nucleosynthesis in planetary nebulae: An origins story
Frontiers in Astronomy and Space Sciences, 2022 I relate an anecdotal history of the beginnings of a new initiative in studies of the chemical composition of planetary nebulae: namely, investigating abundances of elements beyond the iron-peak through infrared spectroscopy.

The Astrophysical Journal, 2023 We have studied the evolution of HuBi 1–like planetary nebulae, considering several stages of mass injection. We have carried out numerical ionization+1D hydrodynamics+atomic/ionic rate models with our code Coral1d to reproduce planetary nebulae that ...

When the Stars Align: A 5σ Concordance of Planetary Nebulae Major Axes in the Center of Our Galaxy
The Astrophysical Journal Letters, 2023 We report observations of a remarkable major axes alignment nearly parallel to the Galactic plane of 5 σ significance for a subset of bulge “planetary nebulae” (PNe) that host, or are inferred to host, short-period binaries. Nearly all are bipolar. It is

Infrared Observations of Planetary Nebulae and Related Objects
Galaxies, 2020 In this paper, I present how near and mid-infrared observations can be used for the study of planetary nebulae and related objects. I present the main observing techniques, from the ground and space, highlighting main differences and how they can be ...

Integral Field Spectroscopy of Planetary Nebulae with MUSE
Galaxies, 2020 The Multi-Unit Spectroscopic Explorer (MUSE) is a large integral field unit mounted on the ESO Very Large Telescope. Its spatial (60 arcsecond field) and wavelength (4800–9300Å) coverage is well suited to detailed imaging spectroscopy of extended ...
