    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...

    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...

    A theoretical investigation of the possible detection of C24 in space
    Astronomical infrared spectral features at ~6.6, 9.8 and 20 micronm have recently been suggested as being due to the planar graphene form of C24 carbon cluster...

    A Third Massive Star Component in the σ Orionis AB System
    We report on the detection of a third massive star component in the σ Orionis AB system, traditionally considered as a binary system. The system has been...

    A tidally tilted sectoral dipole pulsation mode in the eclipsing binary TIC 63328020
    We report the discovery of the third tidally tilted pulsator, TIC 63328020. Observations with the TESS satellite reveal binary eclipses with an orbital period...

    A unified model for age-velocity dispersion relations in Local Group galaxies: disentangling ISM turbulence and latent dynamical heating
    We analyse age-velocity dispersion relations (AVRs) from kinematics of individual stars in eight Local Group galaxies ranging in mass from Carina (M* ˜ 106 M⊙)...
