    An extension of Herschel's method for dense and extensive catalogues. Application to the determination of solar motion
    We present a way of handling and interpreting stellar proper motions, in which the idea of substituting them by great circles, proposed by Herschel in 1783...

    An extremely wide and very low-mass pair with common proper motion. Is it representative of a nearby halo stream?
    Aims: We describe the discovery of an extremely wide pair of low-mass stars with a common large proper motion and discuss their possible membership in a...

    An HST/WFPC2 survey of bright young clusters in M 31. IV. Age and mass estimates
    Aims: We present the main results of an imaging survey of possible young massive clusters (YMC) in M 31 performed with the Wide Field and Planetary Camera 2...

    An HST/WFPC2 survey of bright young clusters in M31. I. VdB0, a massive star cluster seen at t ≃ 25 Myr
    Aims: We introduce our imaging survey of possible young massive globular clusters in M31 performed with the Wide Field and Planetary Camera 2 (WFPC2) on the...

    An hydrodynamical model of the barred galaxy NGC 5850
    We present the results of hydrodynamical model calculations of the barred galaxy NGC 5850 and compare to HI observations. The models assume a mass distribution...

    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 imaging spectroscopic survey of the planetary nebula NGC 7009 with MUSE★
    Aims: The spatial structure of the emission lines and continuum over the 50″ extent of the nearby, O-rich, PN NGC 7009 (Saturn Nebula) have been observed with...

    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 in-depth study of HD 174966 with CoRoT photometry and HARPS spectroscopy. Large separation as a new observable for δ Scuti stars
    Aims: The aim of this work was to use a multi-approach technique to derive the most accurate values possible of the physical parameters of the δ Sct star HD...
