    A relic from a past merger event in the Large Magellanic Cloud

    According to the standard cosmological scenario, the large galaxies that we observe today have reached their current mass via mergers with smaller galaxy satellites1. This hierarchical process is expected to take...

    Comprehensive Abundance Measurements in Damped Lyα Systems

    The high quality, high-resolution UVES/VLT and HIRES/Keck spectra of 10 quasars allowed us to analyze in detail 11 intervening damped Lyα systems at z abs = 1.7 – 2.5. We detect...

    Chemical Evolution of Late-Type Dwarfs

    After reviewing some general properties of late-type dwarf galaxies, we present and discuss chemical evolution models for two windy starburst dwarfs: NGC 1569 and NGC1705. Both have their recent star formation...

    The Effects of Pop III Stars on the Abundances of Spheroids

    We have studied the effects of an hypothetical initial generation made only of very massive stars (M > 100M ⊙, pair-creation SNe) on the chemical and photometric evolution of spheroidal sy...

    The Chemical Evolution of Dwarf Spheroidals

    We describe some models for the chemical evolution of dwarf spheroidals of the Local Group: Draco, Sagittarius, Sculptor, Sextan, Ursa Minor and Carina. These models assume one long or at maximum two episodes ...

    N/O Abundance Ratios: Milky Way and DLAs

    It has been recently shown in Chiappini et al. [2] that models of chemical evolution computed with the Meynet & Maeder [4] yields for the whole range of masses, predict a slower increase of N with respect to w...

    Metallicity in Open Clusters

    We present here the results of abundance measurements of iron, calcium and nickel in four open clusters, from UVES spectra of solar–type stars. A code developed by one of the authors (François) performs line r...

    Abundances in the interstellar medium

    Recent developments in the theory of element production and the chemical evolution of the galaxy are presented. Following this, observational data and their interpretation are given. A case by case analysis of...
