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…
The aeolian-erosion barrier for the growth of metre-size objects in protoplanetary-discs
Mor Rozner, Evgeni Grishin, Hagai B. Perets
Aeolian-erosion is a destructive process which can erode small-size planetary objects through their interaction with a gaseous environment. Aeolian-erosion operates in a wide range…
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…
Multiple Impact Origin for the Moon
Raluca Rufu, Oded Aharonson, Hagai B. Perets
The hypothesis of lunar origin by a single giant impact can explain some aspects of the Earth-Moon system. However, it is difficult to reconcile giant impact models with the compos…
