The iconic planetary nebula (PN) NGC 7027 is bright, nearby (D∼ 1 kpc), highly ionized,
intricately structured, and well observed. This nebula is hence an ideal case study for …

Here we present the spatially resolved study of six Galactic planetary nebulae (PNe),
namely IC 4593, Hen 2-186, Hen 2-429, NGC 3918, NGC 6543, and NGC 6905, from …

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+ …

We present a brief review of the formation and evolution of hydrogen-deficient central stars
of planetary nebulae. We include a detailed description of the main observable features of …

We present the analysis of spatially resolved spectroscopic observations of the born-again
planetary nebula (PN) A 78 that are used to investigate the chemistry and physical …

We present the analysis of Multi-Espectrógrafo en GTC de Alta Resolución para Astronomía
(MEGARA) high-dispersion integral field spectroscopic observations of the bipolar planetary …

Born-again planetary nebulae (PNe) are extremely rare cases in the evolution of solar-like
stars. It is commonly accepted that their central stars (CSPN) experienced a very late thermal …

IRAS 22568+ 6141 has been classified as a low-excitation planetary nebula (PN) and
presents non-thermal radio continuum emission, which could be a signature of a nascent …

Born-again planetary nebulae (PNs) allow investigating stellar evolution, dust production,
and nebular shocks in human timescales. Here we present an analysis of multiepoch optical …

We present a brief review on the formation and evolution of hydrogen deficient central stars
of planetary nebulae. We include a detailed description of the main observable features of …
