    On the wind momentum problem of O-type stars in the galaxy
    We have examined the wind momentum problem of O-type stars in the Galaxy. It is shown that the discrepancy between theoretical and empirical mass loss rates and...

    On the α-Element Abundance Gradients in the Disk of the Sculptor Spiral Galaxy NGC 300
    We have carried out a detailed spectral analysis of six early B-type supergiants in the Sculptor Group spiral galaxy NGC 300. To this end, we used state-of-the...

    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...

  • Publication
    On ɛ-mechanism-driven pulsations in VV 47
    We report new observations of the central star of the planetary nebula VV 47 carried out to verify earlier assertions that the short-period pulsation modes...
  • Publication
    On-sky demonstration of matched filters for wavefront measurements using ELT-scale elongated laser guide stars
    The performance of adaptive optics systems is partially dependent on the algorithms used within the real-time control system to compute wavefront slope...

    Once in a blue moon: detection of `bluing' during debris transits in the white dwarf WD 1145+017
    The first transiting planetesimal orbiting a white dwarf was recently detected in K2 data of WD 1145+017 and has been followed up intensively. The multiple...

    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...

    One Planet or Two Planets? The Ultra-sensitive Extreme-magnification Microlensing Event KMT-2019-BLG-1953
    We present the analysis of a very high-magnification (A ∼ 900) microlensing event KMT-2019-BLG-1953. A single-lens single-source (1L1S) model appears to...
