    HADES RV programme with HARPS-N at TNG. XII. The abundance signature of M dwarf stars with planets
    Context. Most of our current knowledge on planet formation is still based on the analysis of main sequence, solar-type stars. Conversely, detailed chemical...

    HADES RV programme with HARPS-N at TNG. XIV. A candidate super-Earth orbiting the M-dwarf GJ 9689 with a period close to half the stellar rotation period
    Context. It is now well-established that small, rocky planets are common around low-mass stars. However, the detection of such planets is challenged by the...

    HADES RV Programme with HARPS-N at TNG. XV. Planetary occurrence rates around early-M dwarfs
    Aims: We present the complete Bayesian statistical analysis of the HArps-n red Dwarf Exoplanet Survey (HADES), which monitored the radial velocities of a large...

    HD 110067 c has an aligned orbit. Measuring the Rossiter-McLaughlin effect inside a resonant multi-planet system with ESPRESSO
    Planetary systems in mean motion resonances hold a special place among the planetary population. They allow us to study planet formation in great detail as...

    HD 137510: An Oasis in the Brown Dwarf Desert
    Since the beginning of precise Doppler surveys, which have had stunning success in detecting extrasolar planetary companions, one surprising enigma has emerged...

    HD 144548: A young triply eclipsing system in the Upper Scorpius OB association
    The star HD 144548 (=HIP 78977; TYP 6212-1273-1) has been known as a detached eclipsing binary and a bona-fide member of the Upper Scorpius OB association...

    HD 17156b: a transiting planet with a 21.2-day period and an eccentric orbit
    We report the detection of transits by the 3.1 M_Jup companion to the V=8.17 G0V star HD 17156. The transit was observed by three independant observers on Sep...

    HD 191939 revisited: New and refined planet mass determinations, and a new planet in the habitable zone
    HD 191939 (TOI-1339) is a nearby (d = 54 pc), bright (V = 9 mag), and inactive Sun-like star (G9 V) known to host a multi-planet transiting system. Ground-based...

    HD 20329b: An ultra-short-period planet around a solar-type star found by TESS
    Context. Ultra-short-period (USP) planets are defined as planets with orbital periods shorter than one day. This type of planets is rare, highly irradiated, and...
