Description
Abundance determinations in planetary nebulae (PNe) are crucial for understanding stellar evolution and the chemical evolution of the host galaxy. We discuss the complications involved when the presence of a metal-rich phase is suspected in the nebula. We demonstrate that the presence of a cold region emitting mainly metal recombination lines necessitates a detailed treatment to obtain an accurate assessment of the enrichment of this cold gas phase.

    Ground-based observations of (65803) Didymos 2.5 years after the DART impact: searching for ongoing evolution
    On 2022 September 26, NASA's DART mission intentionally impacted Dimorphos, the moon of near-Earth asteroid (65803) Didymos, changing the binary system's orbital period. The system was studied intensively from the ground over the ensuing months until February 2023 when its brightness and low solar elongation precluded further observations. These

    An Ultra-hot Low-mass Brown Dwarf Eclipsing the Puffy White Dwarf J0404+1112
    Most exoplanets known orbit stars that will evolve into red giants, then white dwarfs (WDs). Understanding the population of substellar WD companions informs the common-envelope evolution process (E. Villaver & M. Livio 2009), thereby shedding light on the current and future planetary population of the Milky Way. Here, we report the discovery of a

    The abundance discrepancy in ionized nebulae: which are the correct abundances?
    Ionized nebulae are key to understanding the chemical composition and evolution of the Universe. Among these nebulae, H II regions and planetary nebulae are particularly important as they provide insight into the present and past chemical composition of the interstellar medium, along with the nucleosynthetic processes involved in the chemical
