JWST observations of the planetary nebula NGC 6302 IV: PAH spectral characteristics, formation and evolution
Nicholas Clark, Els Peeters, Jan Cami +29
Polycyclic aromatic hydrocarbons (PAHs) and carbonaceous dust have been observed in Oxygen-rich planetary nebulae (PNe), yet their formation and evolution in these environments is…
Detection of CH3+ in the O-rich planetary nebula NGC 6302
Charmi Bhatt, Jan Cami, Els Peeters +33
Planetary nebulae are sites where ejected stellar material evolves into complex molecules, but the precise physical conditions and chemical routes that govern these processes are u…
Recalibration of the H surface brightness-radius relation for planetary nebulae using Gaia DR3: new distances and the Milky Way oxygen radial gradient
Oscar Cavichia, Hektor Monteiro, Miguel Cerviño +3
The spatial distribution of chemical elements in the Galactic disk provides key constraints on models of galaxy evolution. However, studies using planetary nebulae (PNe) as tracers…
Detection of the [C I] 8727 emission line. Low-ionization structures in NGC 7009
Stavros Akras, Hektor Monteiro, Jeremy R. Walsh +5
We report the first spatially resolved detection of the near-infrared [C I] 8727 emission from the outer pair of low-ionization structures in the planetary nebula NGC 7009 from…
Abundance determination in PNe: How to deal with large chemical inhomogeneities
Christophe Morisset, Jorge Garcia-Rojas, Veronica Gomez-Llanos +1
Abundance determinations in planetary nebulae (PNe) are crucial for understanding stellar evolution and the chemical evolution of the host galaxy. We discuss the complications invo…
