    Parsec-scale Dust Emission from the Polar Region in the Type 2 Nucleus of NGC 424
    Advancements in infrared (IR) interferometry open up the possibility to spatially resolve active galactic nuclei (AGNs) on the parsec-scale level and study the...

    PASS: An All Sky Survey for the Detection of Transiting Extrasolar Planets and for Permanent Variable Star Tracking
    An overview is given of the Permanent All Sky Survey (PASS) project. The primary goal of PASS is the detection of all transiting giant planets in the entire sky...

    Period, epoch, and prediction errors of ephemerides from continuous sets of timing measurements
    Space missions such as Kepler and CoRoT have led to large numbers of eclipse or transit measurements in nearly continuous time series. This paper shows how to...

    Phase diversity restoration of sunspot images. I. Relations between penumbral and photospheric features
    We investigate the dynamics of and the relations between small-scale penumbral and photospheric features near the outer penumbral boundary: penumbral grains...

    Photo-dynamical characterisation of the TOI-178 resonant chain. Exploring the robustness of transit-timing variations and radial velocity mass characterisations
    Context. The TOI-178 system consists of a nearby, late-K-dwarf with six transiting planets in the super-Earth to mini-Neptune regime, with radii ranging from to...
