    What stars can tell us about galaxies: star formation histories in the Local Group
    The formation and evolution of Local Group galaxies can be studied in the greatest possible detail thanks to the possibility of obtaining photometry and...

    When binaries keep track of recent nucleosynthesis
    We determine Zr and Nb elemental abundances in barium stars to probe the operation temperature of the s-process that occurred in the companion asymptotic giant...

    When disks collide: major and minor mergers in disk galaxies
    We present the surface brightness profile fitting of a sample of double nucleus disk galaxies, minor merger candidates. We have decomposed these systems into...

    When stars speak too fast: probing the first dredge up beyond the Nyquist frequency
    Using asteroseismology, we analyse late subgiants and early red giants with long cadence data from Kepler. These two phases are key for studying the first...

    Where have all the bulges gone?
    Several recent studies indicate that bulges are more complex than merely structureless relaxed stellar systems. We study the HST images of a sample of 130...

    Which galaxy mass estimator can we trust?
    We address the problem that dynamical masses of high-redshift massive galaxies, derived using virial scaling, often come out lower than stellar masses inferred...
