Descripción
We have obtained for the first time 2.10 - 2.45 micron infrared spectra of soft X-ray transient V404 Cygni. We determine a 95 percent confidence upper limit to the fraction of light arising from the accretion disc of 14 percent. The effect this has on the mass of the compact object, determined from modelling the infrared ellipsoidal variations, is to reduce its mass to at most 10 M(solar mass).

    Primitive asteroids in the Main Belt possess one of the most pristine inventories of materials in the Solar System. Main Belt primitive asteroids are particularly interesting due to clear evidence of phyllosilicates, i.e., silicates that have encountered liquid water and undergone chemical alteration. Since asteroids are thought to be likely

    NEOMIR: project statut of ESA's space-based infrared mission for NEO detection and early warning
    To warn about potential asteroid or comet impacts, we must first observe and discover these objects through dedicated NEO surveys. Most current and planned surveys are ground-based and use visible light, but they face limitations like weather dependency, limited sky visibility, difficulty detecting at low galactic latitudes, and inability to
