    An image of the dust sublimation region in the nucleus of NGC 1068
    We present near-infrared interferometric data on the Seyfert 2 galaxy NGC 1068, obtained with the GRAVITY instrument on the European Southern Observatory Very...

    An impressionist view of V Hydrae. When MATISSE paints asymmetric giant blobs
    Context. Asymptotic giant branch (AGB) stars enrich the interstellar medium through their mass loss. The mechanism(s) shaping the circumstellar environment of...

    An Infrared Census of DUST in Nearby Galaxies with Spitzer (DUSTiNGS). IV. Discovery of High-redshift AGB Analogs
    The survey for DUST in Nearby Galaxies with Spitzer (DUSTiNGS) identified several candidate Asymptotic Giant Branch (AGB) stars in nearby dwarf galaxies and...

    An M dwarf accompanied by a close-in giant orbiter with SPECULOOS
    In the last decade, a dozen close-in giant planets have been discovered orbiting stars with spectral types ranging from M0 to M4, a mystery since known...

    An optical transmission spectrum of the giant planet WASP-36 b
    We present broad-band photometry of five transits in the planetary system WASP-36, totalling 17 high-precision light curves. Four of the transits were...

    An ultra-short period rocky super-Earth orbiting the G2-star HD 80653★
    Ultra-short period (USP) planets are a class of exoplanets with periods shorter than one day. The origin of this sub-population of planets is still unclear...

    An ultra-short-period transiting super-Earth orbiting the M3 dwarf TOI-1685
    Dynamical histories of planetary systems, as well as the atmospheric evolution of highly irradiated planets, can be studied by characterizing the ultra-short...

    An unusually low-density super-Earth transiting the bright early-type M-dwarf GJ 1018 (TOI-244)
    Context. Small planets located at the lower mode of the bimodal radius distribution are generally assumed to be composed of iron and silicates in a proportion...

    An updated MILES stellar library and stellar population models
    Aims: We present a number of improvements to the MILES library and stellar population models. We correct some small errors in the radial velocities of the stars...
