    Radial gradients of CO absorptions and abundance ratios in the bulge of M31
    We present new H- and K-band spectroscopy for the bulge of M31, taken with the LUCI spectrograph at the Large Binocular Telescope (LBT). We studied radial...

    Radial velocity follow-up of GJ1132 with HARPS. A precise mass for planet b and the discovery of a second planet
    The source GJ1132 is a nearby red dwarf known to host a transiting Earth-size planet. After its initial detection, we pursued an intense follow-up with the...

    Radii, masses, and transit-timing variations of the three-planet system orbiting the naked-eye star TOI-396
    Context. TOI-396 is an F6 V bright naked-eye star (V ≈ 6.4) orbited by three small (R p ≈ 2 R ⊕) transiting planets discovered thanks to space-based photometry...

    Radio emission in a nearby, ultra-cool dwarf binary: A multifrequency study
    Context. The substellar triple system VHS J125601.92−125723.9 (hereafter VHS 1256−1257) is composed of an equal-mass M7.5 brown dwarf binary and an L7 low-mass...
