Origin of (2014) MU69-like Kuiper-belt contact binaries from wide binaries
Evgeni Grishin, Uri Malamud, Hagai B. Perets +2
Following its flyby and first imaging the Pluto-Charon binary, the New Horizons spacecraft visited the Kuiper-Belt-Object (KBO) (486958) 2014 MU69 (Arrokoth). Imaging showed MU69 t…
Tidal disruption of planetary bodies by white dwarfs II: Debris disc structure and ejected interstellar asteroids
Uri Malamud, Hagai Perets
We make use of a new hybrid method to simulate the long-term, multiple-orbit disc formation through tidal disruptions of rocky bodies by white dwarfs, at high-resolution and realis…
Tidal disruption of planetary bodies by white dwarfs I: A hybrid SPH-analytical approach
Uri Malamud, Hagai Perets
We introduce a new hybrid method to perform high-resolution tidal disruption simulations, at arbitrary orbits. An SPH code is used to simulate tidal disruptions only in the immedia…
Collisional formation of massive exomoons of super-terrestrial exoplanets
Uri Malamud, Hagai B. Perets, Christoph Schaefer +1
Exomoons orbiting terrestrial or super-terrestrial exoplanets have not yet been discovered; their possible existence and properties are therefore still an unresolved question. Here…
Post-main-sequence evolution of icy minor planets. III. water retention in dwarf planets and exo-moons and implications for white dwarf pollution
Uri Malamud, Hagai B. Perets
Studies suggest that the pollution of white dwarf (WD) atmospheres arises from the accretion of minor planets, but the exact properties of polluting material, and in particular the…
Post main sequence evolution of icy minor planets II: water retention and white dwarf pollution around massive progenitor stars
Uri Malamud, Hagai B. Perets
Most studies suggest the pollution of white dwarf (WD) atmospheres arises from accretion of minor planets, but the exact properties of polluting material, and in particular the evi…
