Momentum transfer coefficient constraints for the 2024 PDC25 Hypothetical Asteroid Impact Scenario
Christoph M. Schäfer, Uri Malamud, Tamir Manoach +1
In Epoch 2 of the 2024 PDC25 Hypothetical Asteroid Impact Scenario, an asteroid is confirmed to be on a collision course with the Earth, and its size and surface composition have b…
Realistic outcomes of moon-moon collisions in Lunar formation theory
Uri Malamud, Hagai Perets
The multiple impact hypothesis proposes that the Moon formed through a series of smaller collisions, rather than a single giant impact. This study advances our understanding of thi…
New versus past silica crush curve experiments: application to Dimorphos benchmarking impact simulations
Uri Malamud, Christoph M. Schafer, Irina Luciana San Sebastian +7
Crush curves are of fundamental importance to numerical modeling of small and porous astrophysical bodies. The empirical literature often measures them for silica grains, and diffe…
White dwarf systems: exoplanets and debris disks
Uri Malamud
Although there is abundant and diverse observational evidence in support of white dwarf stars hosting planets or debris disks which form in the catastrophic destruction of various…
A link between the size and composition of comets
James E. Robinson, Uri Malamud, Cyrielle Opitom +2
All cometary nuclei that formed in the early Solar System incorporated radionuclides and therefore were subject to internal radiogenic heating. Previous work predicts that if comet…
Uranus and Neptune as methane planets: producing icy giants from refractory planetesimals
Uri Malamud, Morris Podolak, Joshua Podolak +1
Uranus and Neptune are commonly considered ice giants, and it is often assumed that, in addition to a solar mix of hydrogen and helium, they contain roughly twice as much water as…
