    A DECam view of the diffuse dwarf galaxy Crater II: the colour-magnitude diagram
    We present a deep Blanco/DECam colour-magnitude diagram (CMD) for the large but very diffuse Milky Way satellite dwarf galaxy Crater II. The CMD shows only old...

    A deep look into the core of young clusters. II. λ-Orionis
    Context: Over the past years, the λ-Orionis cluster has been a prime location for the study of young very low mass stars, substellar and isolated planetary mass...

    A deep look into the cores of young clusters. I. σ-Orionis
    Context: Nearby young clusters are privileged places to study the star formation history. Over the last decade, the σ-Orionis cluster has been a prime location...

    A Deep View of the Monoceros Ring in the Anticenter Direction: Clues of Its Extra-galactic Origin
    We present the results of deep imaging obtained at the Canada-France-Hawaii Telescope with MegaCam in the anticenter direction at two different heights above...

    A deep wide-field optical survey in the young open cluster Collinder 359
    We present the first deep, optical, wide-field imaging survey of the young open cluster Collinder 359, complemented by near-infrared follow-up observations...

    A deeper view of the CoRoT-9 planetary system. A small non-zero eccentricity for CoRoT-9b likely generated by planet-planet scattering
    CoRoT-9b is one of the rare long-period (P = 95.3 days) transiting giant planets with a measured mass known to date. We present a new analysis of the CoRoT-9...

    A detailed analysis of the Gl 486 planetary system
    Context. The Gl 486 system consists of a very nearby, relatively bright, weakly active M3.5 V star at just 8 pc with a warm transiting rocky planet of about 1.3...

    A detailed non-LTE analysis of LB-1: Revised parameters and surface abundances
    Context. It has recently been proposed that LB-1 is a binary system at 4 kpc consisting of a B-type star of 8 M ☉ and a massive stellar black hole (BH) of 70 M...

    A detailed two-dimensional stellar population study of M32
    We present integral field spectroscopy of the 9×12arcsec2 circumnuclear region of M32 obtained with the 2D_FIS fibre optics spectrographs installed at the 4.2-m...
