PublicationB-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...

PublicationCarbon 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...

PublicationCharacterization 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...

PublicationChemical 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...
