    B-type supergiants in the Small Magellanic Cloud: rotational velocities and implications for evolutionary models
    High-resolution spectra for 24 SMC and Galactic B-type supergiants have been analysed to estimate the contributions of both macroturbulence and rotation to the...

    B-type supergiants in the SMC: Chemical compositions and comparison of static and unified models
    High-resolution UCLES/AAT spectra are presented for nine B-type supergiants in the SMC, chosen on the basis that they may show varying amounts of nuclear...

    Carbon and oxygen in H II regions of the Magellanic Clouds: abundance discrepancy and chemical evolution
    We present C and O abundances in the Magellanic Clouds derived from deep spectra of H II regions. The data have been taken with the Ultraviolet-Visual Echelle...

    Characterization of M-stars in the LMC in the JWST era
    We study the M-type asymptotic giant branch (AGB) population of the Large Magellanic Cloud (LMC) by characterizing the individual sources in terms of the main...

    Chemical evolution in star clusters: the role of mass and environment.
    The process of chemical self-enrichment in stellar systems can be affected by the total mass of the system and the conditions of the large-scale environment...
