    Discs of planetary-mass objects in σ Orionis
    Aims:We searched for infrared flux excesses of planetary-mass candidates in the σ Orionis cluster (~3 Myr, ~350 pc). Methods: Using IJHKs data from the...

    Disentangling component spectra of κ Sco, a spectroscopic binary with a pulsating primary. I. Improved physical elements and analysis of periodic rapid variations of scalar quantities
    A new reduction and a new analysis of a rich series of high-S/N spectra of the bright star κ Sco is carried out to test the technique of spectral disentangling...

    Disentangling component spectra of κ Scorpii, a spectroscopic binary with a pulsating primary. II. Interpretation of the line-profile variability
    We analyse the complex short-term SiIII line-profile variability of the spectroscopic binary β Cep star κ Scorpii after orbit subtraction, before and after...

    Disk stars in the Milky Way detected beyond 25 kpc from its center
    Context. The maximum size of the Galactic stellar disk is not yet known. Some studies have suggested an abrupt drop-off of the stellar density of the disk at...

    Disproving the validated planets K2-78b, K2-82b, and K2-92b. The importance of independently confirming planetary candidates
    Context. Transiting super-Earths orbiting bright stars in short orbital periods are interesting targets for the study of planetary atmospheres. Aims: While...

    Dissecting a miniature universe: A multi-wavelength view of galaxy quenching in the Shapley supercluster
    Multiple cluster systems, that is superclusters, contain large numbers of galaxies assembled in clusters interconnected by multi-scale filamentary networks. As...

    Dissecting the cosmic infra-red background with Herschel/PEP
    The constituents of the cosmic IR background (CIB) are studied at its peak wavelengths (100 and 160 μm) by exploiting Herschel/PACS observations of the GOODS-N...

    Dissecting the morphological and spectroscopic properties of galaxies in the local Universe. I. Elliptical galaxies
    Aims: We revisit the scaling relations and star-forming histories of local elliptical galaxies using a novel selection method applied to the Sloan Digital Sky...
