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…
Atmospheric Erosion by Giant Impacts onto Terrestrial Planets
J. A. Kegerreis, V. R. Eke, R. J. Massey +1
We examine the mechanisms by which atmosphere can be eroded by giant impacts onto Earth-like planets with thin atmospheres, using 3D smoothed particle hydrodynamics simulations wit…
