  • Publication
    Rotating ``black holes'' with holes in the horizon
    Kerr-Schild solutions of the Einstein-Maxwell field equations, containing semi-infinite axial singular lines, are investigated. It is shown that axial...
  • Publication
    Rotation and magnetism of Kepler pulsating solar-like stars. Towards asteroseismically calibrated age-rotation relations
    Kepler ultra-high precision photometry of long and continuous observations provides a unique dataset in which surface rotation and variability can be studied...
  • Publication
    Rotation of Hot Horizontal-Branch Stars in the Globular Clusters NGC 1904, NGC 2808, NGC 6093, and NGC 7078
    We present high-resolution Very Large Telescope/Ultraviolet Visual Echelle Spectrograph observations of 56 stars in the extended horizontal-branch (EHB) of the...
  • Publication
    Rotation of Solar Analogs Crossmatching Kepler and Gaia DR2
    A major obstacle to interpreting the rotation period distribution for main-sequence stars from Kepler mission data has been the lack of a precise evolutionary...
  • Publication
    Rotation Period and Lightcurve of Asteroid 338 Budrosa
    Not Available
  • Publication
    Rotation periods and photometric variability of rapidly rotating ultracool dwarfs
    We used the optical and near-infrared imagers located on the Liverpool, the IAC80, and the William Herschel telescopes to monitor 18 M7-L9.5 dwarfs with the...
  • Publication
    Rotation periods of late-type dwarf stars from time series high-resolution spectroscopy of chromospheric indicators
    We determine rotation periods of a sample of 48 late F-type to mid-M dwarf stars using time series high-resolution spectroscopy of the Ca II H&K and H α...
  • Publication
    Rotation rates, sizes and star formation efficiencies of a representative population of simulated disc galaxies
    We examine the rotation rates, sizes and star formation (SF) efficiencies of a representative population of simulated disc galaxies extracted from the Galaxies...
  • Publication
    Rotation velocities of hot horizontal branch stars in the globular clusters NGC 1904, NGC 2808, NGC 6093, and NGC 7078: The database
    We present radial and rotation (v sin i) velocity measurements from UVES+VLT high resolution spectra of 61 stars in the blue horizontal branches (HB) of the...
