    The complex Milky Way history
    In this seminar I will focus on how the avalanche of new data changes our views on how our Galaxy formed and evolved. Precise astrometric, spectroscopic...

    The cosmic waltz of Coma Berenices and Latyshev 2 (Group X). Membership, phase-space structure, mass, and energy distributions
    Context. Open clusters (OCs) are fundamental benchmarks where theories of star formation and stellar evolution can be tested and validated. Coma Berenices (Coma...

    The G-dwarf problem - A tentative analytical approach, relaxing instantaneous recycling
    The general solution for the birth function B(m,t) of stars, derived by Casuso et al. (1989) was used to obtain a first-order analytical approximation to this...

    The Gaia-ESO Survey: radial metallicity gradients and age-metallicity relation of stars in the Milky Way disk
    We study the relationship between age, metallicity, and α-enhancement of FGK stars in the Galactic disk. The results are based upon the analysis of high...

    The interstellar (C-12)H(+)/(C-13)H(+) ratio towards HD 26676
    We present a new determination of the interstellar 12CH+/13CH+ ratio in the solar neighbourhood, based on high spectral resolution CCD observations of the CH+...

    The rotation-metallicity relation for the Galactic disk as measured in the Gaia DR1 TGAS and APOGEE data
    Aims: Previous studies have found that the Galactic rotation velocity-metallicity (V-[Fe/H]) relations for the thin and thick disk populations show negative and...
