    Populations of evolved massive binary stars in the Small Magellanic Cloud: II. Predictions from rapid binary evolution
    Context. Massive star evolution plays a crucial role in astrophysics; however, its study is subject to large uncertainties. This problem becomes more severe by...

    PORTA: A three-dimensional multilevel radiative transfer code for modeling the intensity and polarization of spectral lines with massively parallel computers
    The interpretation of the intensity and polarization of the spectral line radiation produced in the atmosphere of the Sun and of other stars requires solving a...

    Position-velocity diagrams of ionized gas in the inner regions of disk galaxies
    We use long-slit spectroscopy along the major axis of a sample of 23 nearby disk galaxies to study the kinematic properties of the ionized-gas component in...

    Possible detection of phase changes from the non-transiting planet HD 46375b by CoRoT
    Context. The present work deals with the detection of phase changes in an exoplanetary system. HD 46375 is a solar analog known to host a non-transiting Saturn...

    Possible origin of the non-detection of metastable He I in the upper atmosphere of the hot Jupiter WASP-80b
    Aims: We aim to constrain the origin of the non-detection of the metastable He I triplet at ≈10 830 Å obtained for the hot Jupiter WASP-80b. Methods: We measure...

    Possible ring material around centaur (2060) Chiron
    We propose that several short-duration events observed in past stellar occultations by Chiron were produced by ring material. Some similarities between these...

    Post common envelope binaries from SDSS. IV. SDSS J121258.25-012310.1, a new eclipsing system
    From optical photometry we show that SDSS J121258.25-012310.1 is a new eclipsing, post common-envelope binary with an orbital period of 8.06 h and an eclipse...

    Post common envelope binaries from SDSS. VIII. Evidence for disrupted magnetic braking
    Context. The standard prescription of angular momentum loss in compact binaries assumes magnetic braking to be very efficient as long as the secondary star has...

    Post common envelope binaries from SDSS. XII. The orbital period distribution
    Context. The complexity of the common-envelope phase and of magnetic stellar wind braking currently limits our understanding of close binary evolution. Because...
