Immediate origin of the Moon as a post-impact satellite
Jacob A. Kegerreis, Sergio Ruiz-Bonilla, Vincent R. Eke +3
The Moon is traditionally thought to have coalesced from the debris ejected by a giant impact onto the early Earth. However, such models struggle to explain the similar isotopic co…
Dealing with density discontinuities in planetary SPH simulations
Sergio Ruiz-Bonilla, Josh Borrow, Vincent R. Eke +4
Density discontinuities cannot be precisely modelled in standard formulations of smoothed particles hydrodynamics (SPH) because the density field is defined smoothly as a kernel-we…
Measurement of the Free Neutron Lifetime using the Neutron Spectrometer on NASA's Lunar Prospector Mission
Jack T. Wilson, David J. Lawrence, Patrick N. Peplowski +2
We use data from the Lunar Prospector Neutron Spectrometer to make the second space-based measurement of the free neutron lifetime finding $τ_n=887 \pm 14_\text{stat}{\:^{+7}_{-3\:…
The effect of pre-impact spin on the Moon-forming collision
Sergio Ruiz-Bonilla, Vincent R. Eke, Jacob A. Kegerreis +2
We simulate the hypothesised collision between the proto-Earth and a Mars-sized impactor that created the Moon. Amongst the resulting debris disk in some impacts, we find a self-gr…
Atmospheric Erosion by Giant Impacts onto Terrestrial Planets: A Scaling Law for any Speed, Angle, Mass, and Density
Jacob A. Kegerreis, Vincent R. Eke, David C. Catling +3
We present a new scaling law to predict the loss of atmosphere from planetary collisions for any speed, angle, impactor mass, target mass, and body compositions, in the regime of g…
Space-Based Measurement of the Neutron Lifetime using Data from the Neutron Spectrometer on NASA's MESSENGER Mission
Jack T. Wilson, David J. Lawrence, Patrick N. Peplowski +2
We establish the feasibility of measuring the neutron lifetime via an alternative, space-based class of methods, which use neutrons generated by galactic cosmic ray spallation of p…
