    A new sample of massive B-type contact binary candidates from the OGLE survey of the Magellanic Clouds
    Context. Massive contact binaries (CBs) are crucial objects for understanding close binary evolution and stellar mergers. Study of these objects has been...

    A new search for planet transits in NGC 6791
    Context: Searching for planets in open clusters allows us to study the effects of dynamical environment on planet formation and evolution. Aims: Considering the...

    A new stellar library in the region of the CO index at 2.3 μm. New index definition and empirical fitting functions
    Context: The analysis of unresolved stellar populations demands evolutionary synthesis models with realistic physical ingredients and extended wavelength...
  • Publication
    A new visual - near-infrared diagnostic to estimate the metallicity of cluster and field dwarf stars
    We present a theoretical calibration of a new metallicity diagnostic based on the Strömgren index m1 and on visual - near-infrared (NIR) colors to estimate the...

    A new way to measure the distance to NGC1052-DF2
    We have employed a novel way to measure the distance to NGC1052-DF2, using the internal stellar velocity dispersions (σ) of its globular clusters (GCs). We...

    A new α-enhanced super-solar metallicity population
    We performed a uniform and detailed analysis of 1112 high-resolution spectra of FGK dwarfs obtained with the HARPS spectrograph at the ESO 3.6 m telescope (La...

    A new, evolved bipolar planetary nebula.
    Optical imaging and spectroscopy reveal that the ionised region No.252 in the list of Marsalkowa (1974Ap&SS..27....3M), whose photograph is presented in the `...

    A newly identified galaxy group thanks to tidal streams of intragroup light
    Context. In the accretion-driven growth scenario, part of the intracluster light is formed in the group environment. Aims: We report the serendipitous discovery...

    A non-axisymmetric potential for the Milky Way disk
    We provide a purely dynamical global map of the non-axisymmetric structure of the Milky Way disk. For this, we exploited the information contained within the in...
