    Pyodine: an open, flexible reduction software for iodine-calibrated precise radial velocities
    Context. Many telescopes use an iodine (I 2) absorption cell to measure precise radial velocities (RVs), but their data reduction pipelines are all tailored to...

    PyTranSpot: A tool for multiband light curve modeling of planetary transits and stellar spots
    Several studies have shown that stellar activity features, such as occulted and non-occulted starspots, can affect the measurement of transit parameters biasing...

    Qatar Exoplanet Survey: Qatar-7b—A Very Hot Jupiter Orbiting a Metal-rich F-Star
    We present the discovery of Qatar-7b—a very hot and inflated giant gas planet orbiting close to its parent star. The host star is a relatively massive main...

    Radial Velocities of Galactic Halo Stars in Virgo
    We present multi-slit radial velocity measurements for 111 stars in the direction of the Virgo Stellar Stream (VSS). The stars were photometrically selected to...

    Radial velocity confirmation of a hot super-Neptune discovered by TESS with a warm Saturn-mass companion
    We report the discovery and confirmation of the planetary system TOI-1288. This late G dwarf harbours two planets: TOI-1288 b and TOI-1288 c. We combine TESS...

    Radial velocity confirmation of K2-100b: a young, highly irradiated, and low-density transiting hot Neptune
    We present a detailed analysis of HARPS-N radial velocity observations of K2-100, a young and active star in the Praesepe cluster, which hosts a transiting...
