    Revisiting the multi-planetary system of the nearby star HD 20794: Confirmation of a low-mass planet in the habitable zone of a nearby G-dwarf
    Context. Close-by Earth analogs and super-Earths are of primary importance because they will be preferential targets for the next generation of direct imaging...

    Revisiting the transits of CoRoT-7b at a lower activity level
    The first super-Earth with measured radius discovered was CoRoT-7b and it has opened the new field of rocky exoplanet characterisation. To better understand...

    Revisiting the warm sub-Saturn TOI-1710b. The impact of stellar activity on the mass measurement
    The Transiting Exoplanet Survey Satellite (TESS) provides a continuous suite of new planet candidates that need confirmation and precise mass determination from...

    Rings in the haloes of planetary nebulae
    We present a search for rings or arcs in the haloes of planetary nebulae (PNe). We discovered such structures in eight PNe, tripling the sample of PNe with...

    Robust machine learning model of inferring the ex situ stellar fraction of galaxies from photometric data
    We searched for the parameters defined from photometric images to quantify the ex situ stellar mass fraction of galaxies. We created mock images using galaxies...

    Role of host star variability in the detectability of planetary phase curves
    Phase curves, or the change in observed illumination of the planet as it orbits around its host star, help us to characterize their atmospheres. However, the...

    ROOSTER: a machine-learning analysis tool for Kepler stellar rotation periods
    In order to understand stellar evolution, it is crucial to efficiently determine stellar surface rotation periods. Indeed, while they are of great importance in...

    Rotation and magnetism of Kepler pulsating solar-like stars. Towards asteroseismically calibrated age-rotation relations
    Kepler ultra-high precision photometry of long and continuous observations provides a unique dataset in which surface rotation and variability can be studied...

    Rotation velocities of hot horizontal branch stars in the globular clusters NGC 1904, NGC 2808, NGC 6093, and NGC 7078: The database
    We present radial and rotation (v sin i) velocity measurements from UVES+VLT high resolution spectra of 61 stars in the blue horizontal branches (HB) of the...
