    Variability in a Young, L/T Transition Planetary-mass Object
    As part of our ongoing NTT SoFI survey for variability in young free-floating planets and low-mass brown dwarfs, we detect significant variability in the young...
  • Publication
    Variability in the CoRoT photometry of three hot O-type stars. HD 46223, HD 46150, and HD 46966
    Context. The detection of pulsational frequencies in stellar photometry is required as input for asteroseismological modelling. The second short run (SRa02) of...
  • Publication
    Variability of OB stars from TESS southern Sectors 1-13 and high-resolution IACOB and OWN spectroscopy
    Context. The lack of high-precision long-term continuous photometric data for large samples of stars has impeded the large-scale exploration of pulsational...

    Variability of the Ap-Star 21-COMAE-BERENICES - Results from Multiple-Site Campaigns
    A total of over 210 hr of previously unpublished differential photoelectric photometry of 21 Com (HD 108945, HR4766), obtained in five years, were analysed to...
  • Publication
    Variability of the blazar 4C 38.41 (B3 1633+382) from GHz frequencies to GeV energies
    Context. After years of modest optical activity, the quasar-type blazar 4C 38.41 (B3 1633+382) experienced a large outburst in 2011, which was detected...
  • Publication
    Variability of the polarization profiles of the Ba II D{2} line in the solar atmosphere
    Resonance-scattering polarization and the Hanle effect are powerful but seldom exploited probes into the magnetism of the quiet solar atmosphere. They are also...
  • Publication
    Variability of the transitional T Tauri star T Chamaeleontis
    Context: It is known that for solar-mass stars planet formation begins in a circumstellar disc. The study of transitional objects exhibiting clear signs of...

    Variability Survey in the CoRoT SRa01 Field: Implications of Eclipsing Binary Distribution on Cluster Formation in NGC 2264
    Time-series photometry of the CoRoT field SRa01 was carried out with the Berlin Exoplanet Search Telescope II in 2008/2009. A total of 1161 variable stars were...
  • Publication
    Variable central stars of young planetary nebulae. I. Photometric multisite observations of IC 418.
    We report the results of a photometric multisite campaign devoted to HD 35914, the variable central star of the Planetary Nebula IC 418. From the analysis of...
