    The impact of Galactic evolution on binary interactions, as shown in hot subdwarf binaries
    Wide hot subdwarf B (sdB) binaries with main-sequence companions are outcomes of stable mass transfer from evolved red giants. The orbits of these binaries show...

    The integrated galactic IMF - from star clusters to galaxies
    Over the past years observations of young and populous star clusters have shown that the stellar initial mass function (IMF) can be conveniently described by a...

    The non-homology - star-formation connection: hints for the solution of the FP problem
    We present the K band FP of the ETGs members of the clusters observed by the WINGS survey. The data confirm a different tilt of the FP with respect to the V...

    The Pristine survey: An efficient search for extremely metal-poor stars
    The most metal-poor stars in the Galaxy are relics from the first generations of star formation, and their properties can reveal key information about the...
