    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⊙)...

    A very dark stellar system lost in Virgo: kinematics and metallicity of SECCO 1 with MUSE
    We present the results of VLT-MUSE (Very Large Telescope-Multi Unit Spectroscopic Explorer) integral field spectroscopy of SECCO 1, a faint, star-forming...

    A view of the H-band light-element chemical patterns in globular clusters under the AGB self-enrichment scenario
    We discuss the self-enrichment scenario by asymptotic giant branch (AGB) stars for the formation of multiple populations in globular clusters (GCs) by analysing...

    A WFC3/HST View of the Three Stellar Populations in the Globular Cluster NGC 6752
    Multi-band Hubble Space Telescope photometry reveals that the main sequence, sub-giant, and the red-giant branch of the globular cluster NGC 6752 splits into...

    Abell 30 - A binary central star among the born-again planetary nebulae
    Eight planetary nebulae have been identified as 'born-again', a class of object typified by knotty secondary ejecta having low masses (${\sim}10^{-4}$ M ☉) with...

    About Metallicity Variations in the Local Galactic Interstellar Medium
    In this paper we discuss and confront recent results on metallicity variations in the local interstellar medium, obtained from observations of H II regions and...
