Astrophysical: Oort cloud

  • Publication
    Assessing interstellar comet 3I/ATLAS with the 10.4 m Gran Telescopio Canarias and the Two-meter Twin Telescope
    Context. Theories of the formation and evolution of small bodies in planetary systems predict that they may escape into interstellar space at any time, leaked...

    Distant trans-Neptunian object candidates from NASA's TESS mission scrutinized: fainter than predicted or false positives?
    NASA's Transiting Exoplanet Survey Satellite (TESS) is performing a homogeneous survey of the sky from space in search of transiting exoplanets. The collected...

    Euclid: Detecting Solar System objects in Euclid images and classifying them using Kohonen self-organising maps
    The ESA Euclid mission will survey more than 14 000 deg 2 of the sky in visible and near-infrared wavelengths, mapping the extragalactic sky to constrain our...
  • Publication
    Interstellar Visitors and Elusive Extrasolar Meteorites
    Despite the immense voids and vast distances that separate stars, our cosmic neighborhood remains a dynamic stage where emerging phenomena consistently...
  • Publication
    Oort cloud perturbations as a source of hyperbolic Earth impactors
    The observation of interstellar objects 1I/'Oumuamua and 2I/Borisov suggests the existence of a larger population of smaller projectiles that impact our planet...
  • Publication
    Spectroscopic and dynamical properties of comet C/2018 F4, likely a true average former member of the Oort cloud
    Context. The population of comets hosted by the Oort cloud is heterogeneous. Most studies in this area have focused on highly active objects, those with small...

    Surface composition and dynamical evolution of two retrograde objects in the outer solar system: 2008 YB3 and 2005 VD
    Most of the objects in the trans-Neptunian belt (TNb) and related populations move in prograde orbits with low eccentricity and inclination. However, the list...
