    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...

    Post common envelope binaries from SDSS. XIII. Mass dependencies of the orbital period distribution
    Context. Post-common-envelope binaries (PCEBs) consisting of a white dwarf (WD) and a main-sequence secondary star are ideal systems to constrain models of...

    Post first dredge-up [C/N] ratio as age indicator. Theoretical calibration
    We performed a detailed analysis of the use of [C/N] measured in red giant branch stars between the completion of the first dredge up and the red giant branch...

    Post-AGB stars with hot circumstellar dust: binarity of the low-amplitude pulsators
    Context: The influence of binarity on the late stages of stellar evolution remains an open issue. Aims: While the first binary post-AGB stars were...

    Power spectra comparison between GOLF and spatially masked MDI velocity signals
    The Global Oscillations at Low Frequency (GOLF) and the Michelson Doppler Imager (MDI) instruments aboard the Solar and Heliospheric Observatory (SOHO) give an...

    Power spectrum of the CODEX clusters
    Aims. We analyze the clustering of galaxy clusters in a large contiguous sample, the Constrain Dark Energy with X-ray (CODEX) sample. We construct a likelihood...

    Pre-main sequence spectroscopic binaries suitable for VLTI observations
    Context: A severe problem for research in star-formation is that the masses of young stars are almost always estimated from evolutionary tracks alone. Since the...

    Precise characterisation of HD 15337 with CHEOPS: A laboratory for planet formation and evolution
    Context. The HD 15337 (TIC 120896927, TOI-402) system was observed by the Transiting Exoplanet Survey Satellite (TESS), revealing the presence of two short...

    Precise mass and radius of a transiting super-Earth planet orbiting the M dwarf TOI-1235: a planet in the radius gap?
    We report the confirmation of a transiting planet around the bright weakly active M0.5 V star TOI-1235 (TYC 4384-1735-1, V ≈ 11.5 mag), whose transit signal was...
