    A Detailed look at Chemical Abundances in Magellanic Cloud Planetary Nebulae. I. The Small Magellanic Cloud
    We present an analysis of elemental abundances of He, N, O, Ne, S, and Ar in Magellanic Cloud planetary nebulae (PNe) and focus initially on 14 PNe in the Small...

    Ages of LMC star clusters using ASAD2
    We use ASAD2, the new version of ASAD (Analyzer of Spectra for Age Determination), to obtain the age and reddening of 27 Large Magellanic Cloud (LMC) clusters...

    Anomalous Cepheids in the Large Magellanic Cloud. Insight into their origin and connection with the star formation history
    Context. The properties of variable stars can give independent constraints on the star formation history of the host galaxy, by determining the age and...
