    A SLUGGS and Gemini/GMOS combined study of the elliptical galaxy M60: wide-field photometry and kinematics of the globular cluster system
    We present new wide-field photometry and spectroscopy of the globular clusters (GCs) around NGC 4649 (M60), the third brightest galaxy in the Virgo cluster...

    A spatial study of the mid-IR emission features in four Herbig Ae/Be stars
    Context: Infrared (IR) spectroscopy and imaging provide a prime tool to study the characteristics of polycyclic aromatic hydrocarbon (PAH) molecules and the...

    A spectral classification system for hydrogen-deficient carbon stars
    Stellar spectral classification has been highly useful in the study of stars. While there is a currently accepted spectral classification system for carbon...

    A state-of-the-art analysis of the dwarf irregular galaxy NGC 6822
    We present a detailed photometric study of the dwarf irregular galaxy NGC 6822 aimed at investigating the properties of its stellar populations and, in...

    A stellar overdensity associated with the Small Magellanic Cloud
    We report the discovery of a stellar overdensity 8° north of the centre of the Small Magellanic Cloud (SMC; Small Magellanic Cloud Northern Over-Density; SMCNOD...

    A stellar stream remnant of a globular cluster below the metallicity floor
    Stellar ejecta gradually enrich the gas out of which subsequent stars form, making the least chemically enriched stellar systems direct fossils of structures...
  • Publicación
    A study of extragalactic planetary nebulae populations based on spectroscopy. I. Data compilation and first findings
    We compile published spectroscopic data and [O III] magnitudes of almost 500 extragalactic planetary nebulae (PNe) in 13 galaxies of various masses and...

    A super-Earth and a mini-Neptune near the 2:1 MMR straddling the radius valley around the nearby mid-M dwarf TOI-2096
    Context. Several planetary formation models have been proposed to explain the observed abundance and variety of compositions of super-Earths and mini-Neptunes...

    A test for asymptotic giant branch evolution theories: planetary nebulae in the Large Magellanic Cloud
    We used a new generation of asymptotic giant branch (AGB) stellar models that include dust formation in the stellar winds to find the links between evolutionary...
