    A new analysis of the 11-year period in OJ287 - Confirmation of its existence
    We have compiled all the available optical B band data on OJ287, between 1890 and 1991. Using this data we have found a period of 11.6 +/- 0.5 yr for the...

    A new and Homogeneous metallicity scale for Galactic classical Cepheids. II. Abundance of iron and α elements
    Context. Classical Cepheids are the most popular distance indicators and tracers of young stellar populations. The key advantage is that they are bright and...

    A New Approach to the Solar Oxygen Abundance Problem
    In this work we present new data that sets strong constraints on the solar oxygen abundance. Our approach, based on the analysis of spectropolarimetric...

    A New Bursting X-Ray Transient: SAX J1750.8-2900
    We have analyzed in detail the discovery measurements of the X-ray burster SAX J1750.8-2900 by the Wide Field Cameras on board BeppoSAX in spring 1997, at a...
  • Publication
    A New Catalog of Homogenized Absorption Line Indices for Milky Way Globular Clusters from High-resolution Integrated Spectroscopy
    We perform integrated spectroscopy of 24 Galactic globular clusters (GGCs). Spectra are observed from one core radius for each cluster with a high wavelength...
  • Publication
    A New Chemo-evolutionary Population Synthesis Model for Early-Type Galaxies. I. Theoretical Basis
    We have developed a new stellar population synthesis model designed to study early-type galaxies. It provides optical and near-infrared colors, and line indices...
  • Publication
    A New Chemo-evolutionary Population Synthesis Model for Early-Type Galaxies. II. Observations and Results
    We present the results of applying a new chemo-evolutionary stellar population model, developed in a previous paper, to new high-quality observational data of...

    A new class of dark matter-free dwarf galaxies?: I. Clues from FCC 224, NGC 1052-DF2, and NGC 1052-DF4
    Context. The discovery of quiescent, dark matter (DM)-deficient ultra-diffuse galaxies (UDGs) with overluminous globular clusters (GCs) has challenged galaxy...
  • Publication
    A New Class of Roche Lobe-filling Hot Subdwarf Binaries
    We present the discovery of the second binary with a Roche lobe-filling hot subdwarf transferring mass to a white dwarf (WD) companion. This 56 minute binary...
