Catalogue of central stars of extragalactic planetary nebulae
W. A. Weidmann, M. B. Mari, R. A. Pignata +3
Context. Central stars of planetary nebulae (CSPNe) are essential for understanding the final evolutionary stages of low- and intermediate-mass stars. However, their study in extra…
Low-ionization structures in planetary nebulae -- IV. The molecular hydrogen counterpart
M. B. Mari, S. Akras, D. R. Gonçalves
Context. Low-ionization structures (LISs), found in all morphological types of planetary nebulae (PNe), are small-scale features prominent in emission from low-ionization species s…
Unveiling compact planetary nebulae: Broad-band survey analysis and LAMOST confirmation
L. A. Gutiérrez-Soto, M. Belén Mari, W. A. Weidmann +1
Planetary nebulae (PNe) are pivotal for advancing our knowledge of stellar evolution and galactic chemical enrichment. Recent progress in surveys and data analysis has revolutioniz…
Integral field spectroscopy of the planetary nebula NGC 3242 and the puzzling nature of its low ionization structures
L. Konstantinou, S. Akras, J. Garcia-Rojas +7
The physico-chemical properties of the planetary nebula (PN) NGC 3242 are investigated in both 1D and 2D, using Integral Field Unit (IFU) data. This PN has a complex morphology wit…
