Diagnostic diagrams of electron density - excitation for a sample of 613 planetary nebulae are presented. The present extensive sample allows the definition of new statistical limits for the distribution of planetary nebulae in the log [Ha/[SII]] vs log [Ha/[NII]], log [Ha/[SII]] vs [SII] 6717/6731 and log [Ha/[NII]] vs [SII] 6717/6731 planes. The diagrams provide a good representation of the ranges of physical conditions, indicated by these emission line ratios, present in planetary nebulae during different evolutionary stages.

  1. Dissecting NGC 3132: Tracing the mass-loss history of the southern ring planetary nebula

    astro-ph.GA 2025-07 conditional novelty 6.0 of 10

    Applying the empirical abundance method to simulated observations of NGC 3132 from a 3D model overestimates the input oxygen abundance by up to 35% due to line-of-sight projection effects.

  2. Unveiling compact planetary nebulae: Broad-band survey analysis and LAMOST confirmation

    astro-ph.SR 2025-05 conditional novelty 6.0 of 10

    A new Gaia plus Pan-STARRS color-color selection method identifies compact planetary nebulae and yields the discovery of the high-ionization PN J020808.63+491401.0, confirmed by LAMOST spectroscopy and Cloudy modeling.
