    On the Use of Field RR Lyrae as Galactic Probes. III. The α-element Abundances
    We provide the largest and most homogeneous sample of α-element (Mg, Ca, Ti) and iron abundances for field RR Lyrae (RRLs; 162 variables) by using high...
  • Publication
    On the Use of Field RR Lyrae as Galactic Probes. V. Optical and Radial Velocity Curve Templates
    We collected the largest spectroscopic catalog of RR Lyrae (RRLs) including ≍20,000 high-, medium-, and low-resolution spectra for ≍10,000 RRLs. We provide the...
  • Publication
    On the Use of Field RR Lyrae As Galactic Probes: IV. New Insights Into and Around the Oosterhoff Dichotomy
    We discuss the largest and most homogeneous spectroscopic data set of field RR Lyrae variables (RRLs) available to date. We estimated abundances using both high...
  • Publication
    On the White Dwarf Cooling Sequence of the Globular Cluster ω Centauri
    We present deep and precise photometry (F435W, F625W, F658N) of ω Cen collected with the Advanced Camera for Surveys (ACS) on board the Hubble Space Telescope...
  • Publication
    On the ΔV bump HB Parameter in Globular Clusters
    We present new empirical estimates of the ΔV bump HB parameter for 15 Galactic globular clusters (GGCs) using accurate and homogeneous ground-based optical data...

    Ondřejov Echelle Spectrograph, Ground Based Support Facility for Exoplanet Missions
    Fulfilling the goals of space-based exoplanetary transit surveys, like Kepler and TESS, is impossible without ground-based spectroscopic follow-up. In...

    Ongoing star formation at the outskirts of Sextans A: spectroscopic detection of early O-type stars
    With both nebular- and stellar-derived abundances of ≲1/10 Z_{⊙ } and low foreground extinction, Sextans A is a prime candidate to replace the Small Magellanic...
  • Publication
    Open Cluster Chemical Homogeneity throughout the Milky Way
    The chemical homogeneity of surviving stellar clusters contains important clues about interstellar medium (ISM) mixing efficiency, star formation, and the...

    Optical identification of the binary companion to the millisecond PSR J2302+4442 with the Gran Telescopio Canarias
    We report detection of the binary companion to the millisecond pulsar J2302+4442 based on the deep observations performed with the Gran Telescopio Canarias. The...
