Planetary nebulae (PNe) represent the final link in the chain of the gas and dust enrichment of low- and intermediate-mass stars. We present a comprehensive study of the relevant observational data of 10 PNe of the Large Magellanic Cloud (LMC). Analysing them from the UV to the IR, we characterise the nature of the central star (CS) and the dust

In this work, we present the first results of the ATLAS (Asteroid Terrestrial-impact Last Alert System) unit installed by the Instituto de Astrofisica de Canarias (IAC) at Teide Observatory (TO) on Tenerife Island, Spain, in January 2025. The ATLAS-Teide unit operate as part of the ATLAS network (https://atlas.fallingstar.com/) under an agreement

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

Gaia astrometry was used to explore the properties of Galactic Post-AGB stars in the literature. DR3 precise parallaxes allowed us to isolate a small group of stars in the direction of the Large Magellanic Cloud (LMC) previously reported as post-AGB stars in the LMC, but that, according to their distances, seem to be located in an intermediate

We present a detailed study of the large-scale shock front in Stephan's Quintet, a by-product of past and ongoing interactions. Using integral-field spectroscopy from the new William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE), recent 144 MHz observations from the LOFAR Two-metre Sky Survey, and archival data from the Very Large

Context. (2060) Chiron is a large centaur that has been reported active on multiple occasions at relatively large heliocentric distances, including during aphelion passage. Studies of Chiron's coma during active periods have resulted in the detection of C≡N and CO outgassing. Additionally, Chiron is surrounded by a disk of debris that varies with
