Confirmation and characterization of Galactic planetary nebulae: insights from a spectroscopic study
D. A. Beleño-Molina, L. OlguÃn, L. F. Miranda +2
We present a spectroscopic investigation of 25 objects previously reported as possible Planetary Nebulae (PNe) in recent catalogs to obtain their physical properties and to establi…

Long and short term variability of the possible nascent planetary nebula IRAS 22568+6141: A late thermal pulse?
Roldán A. Cala, Luis F. Miranda, José F. Gómez +4
IRAS 22568+6141 has been classified as a low-ionisation planetary nebula (PN) and presents non-thermal radio continuum emission, which could be a signature of nascent PNe. We prese…

Morphokinematical study of the planetary nebula Me2-1: Unveiling its point-symmetric and unusual physical structure
L. F. Miranda, R. Vázquez, L. OlguÃn +2
(Abridged) We present narrow-band images in several emission lines, and high- and intermediate-resolution long-slit spectra of Me2-1 to investigate its morphology and 3D structure,…
