    A search for solar-like oscillations in the stars of M67 with CCD ensemble photometry on a network of 4 M telescopes
    Results are presented from a large observational project directed toward the detection of solar-like oscillations in an ensemble of open cluster stars. Seven...

    A Search for Spectral Hysteresis and Energy-dependent Time Lags from X-Ray and TeV Gamma-Ray Observations of Mrk 421
    Blazars are variable emitters across all wavelengths over a wide range of timescales, from months down to minutes. It is therefore essential to observe blazars...

    A Search for Stellar Populations in High-Velocity Clouds
    We report the results of a photometric search for giant stars associated with the cores of four high-velocity clouds (HVCs)-two of which are compact HVCs-using...

    A search for stellar tidal debris of defunct dwarf galaxies around globular clusters in the inner Galactic halo
    In the hierarchical formation scenario in which the outer halo of the Milky Way is the result of the continuous accretion of low-mass galaxies, a fraction of...

    A search for substellar members in the Praesepe and σ Orionis clusters
    We have conducted deep photometric searches for substellar members of the Praesepe (0.5-1 Gyr) and σ Orionis (3 Myr) star clusters using the Sloan i' and z'...

    A Search for the Optical Counterpart to the Magnetar CXOU J010043.1-721134
    After our tentative detection of an optical counterpart to CXOU J010043.1-721134 from archival Hubble Space Telescope (HST) imaging, we have followed up with...

    A search for transiting planets around hot subdwarfs. I. Methods and performance tests on light curves from Kepler, K2, TESS, and CHEOPS
    Context. Hot subdwarfs experienced strong mass loss on the red giant branch (RGB) and are now hot and small He-burning objects. These stars constitute excellent...

    A Search for Very High Energy Gamma-Ray Emission from Scorpius X-1 with the Magic Telescopes
    The acceleration of particles up to GeV or higher energies in microquasars has been the subject of considerable theoretical and observational efforts in the...

    A Search for Very Low Mass Stars and Brown Dwarfs in the Young sigma Orionis Cluster
    We present a CCD-based photometric survey covering 870 arcmin^2 in a young stellar cluster around the young multiple star sigma Orionis. Our survey-limiting R...
