    A pulsation analysis of K2 observations of the subdwarf B star PG 1142-037 during Campaign 1: A subsynchronously rotating ellipsoidal variable
    We report a new subdwarf B pulsator, PG 1142-037, discovered during the first full-length campaign of K2, the two-gyro mission of the Kepler space telescope. 14...

    A Pulsational Distance to ω Centauri Based on Near-Infrared Period-Luminosity Relations of RR Lyrae Stars
    We present new near-infrared (J and K) magnitudes for 114 RR Lyrae stars in the globular cluster ω Centauri (NGC 5139), which we combine with data from the...

    A pulse-timing model for pulsars in massive eclipsing binaries. Delays caused by high ratios between the pulsar period and orbital length.
    We study the delay induced by gravitational light bending in the arrival times of signals emitted by an anisotropic source in rotation (pulsar). The shift of...

    A QSO Discovered at the Redshift of the Extended X-Ray Cluster RX J0152.7-1357
    The galaxy cluster RX J0152.7-1357 at z=0.8325 is one of the most luminous X-ray clusters known. It is elongated toward the bright, nearby, X-ray active galaxy...

    A qualitative interpretation of the second solar spectrum of Ce ll
    This is a theoretical investigation on the formation of the linearly polarized line spectrum of ionized cerium in the sun. We calculate the scattering line...

    A qualitative interpretation of the second solar spectrum of Ti I
    The first theoretical investigation of the formation of the linearly polarized solar line spectrum of a complex atom, neutral titanium, is presented. The...

    A quantitative demonstration that stellar feedback locally regulates galaxy growth
    We have applied stellar population synthesis to 500-pc-sized regions in a sample of 102 galaxy discs observed with the MUSE spectrograph. We derived the star...

    A quantitative in-depth analysis of the prototype sdB+BD system SDSS J08205+0008 revisited in the Gaia era
    Subdwarf B stars are core-helium-burning stars located on the extreme horizontal branch (EHB). Extensive mass loss on the red giant branch is necessary to form...
