    Determining the dynamics and magnetic fields in He I 10830 Å during a solar filament eruption
    Aims: We investigate the dynamics and magnetic properties of the plasma, including the line-of-sight velocity (LOS) and optical depth, as well as the vertical...

    Determining the full satellite population of a Milky Way-mass halo in a highly resolved cosmological hydrodynamic simulation
    We investigate the formation of the satellite galaxy population of a Milky Way-mass halo in a very highly resolved magnetohydrodynamic cosmological zoom-in...
  • Publication
    Differential image motion in astrometric observations with very large seeing-limited telescopes
    Aims. We investigate how to quantitatively model the observed differential image motion (DIM) in relative astrometric observations. Methods. As a test bed we...

    Discovery and physical characterization as the first response to a potential asteroid collision: The case of 2023 DZ<SUB>2</SUB>
    Context. Near-Earth asteroids (NEAs) that may evolve into impactors deserve detailed threat assessment studies. Early physical characterization of a would-be...

    Discovery of a red ultra-diffuse galaxy in a nearby void based on its globular cluster luminosity function
    Distance determinations of extremely low-surface-brightness galaxies are expensive in terms of spectroscopic time. Because of this, their distances are often...

    Discovery of Tidal Tails Around the Distant Globular Cluster Palomar 14
    We report the detection of a pair of degree-long tidal tails associated with the globular cluster Palomar 14, using images obtained at the Canada-France-Hawaii...

    Discovery of XO-6b: A Hot Jupiter Transiting a Fast Rotating F5 Star on an Oblique Orbit
    Only a few hot Jupiters are known to orbit around fast rotating stars. These exoplanets are harder to detect and characterize and may be less common than around...
  • Publication
    Disentangling the formation history of galaxies via population-orbit superposition: method validation
    We present population-orbit superposition models for external galaxies based on Schwarzschild's orbit-superposition method, by tagging the orbits with age and...
  • Publication
    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...
