No dilute core produced in simulations of giant impacts on to Jupiter
T. D. Sandnes, V. R. Eke, J. A. Kegerreis +2
A giant impact has been proposed as a possible formation mechanism for Jupiter's dilute core -- the planet's inferred internal structure in which the transition between its core of…
REMIX SPH -- improving mixing in smoothed particle hydrodynamics simulations using a generalised, material-independent approach
Thomas D. Sandnes, Vincent R. Eke, Jacob A. Kegerreis +4
We present REMIX, a smoothed particle hydrodynamics (SPH) scheme designed to alleviate effects that typically suppress mixing and instability growth at density discontinuities in S…
A recent impact origin of Saturn's rings and mid-sized moons
Luís F. A. Teodoro, Jacob A. Kegerreis, Paul R. Estrada +5
We simulate the collision of precursor icy moons analogous to Dione and Rhea as a possible origin for Saturn's remarkably young rings. Such an event could have been triggered a few…
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…
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…
Planetary Giant Impacts: Convergence of High-Resolution Simulations using Efficient Spherical Initial Conditions and SWIFT
J. A. Kegerreis, V. R. Eke, P. G. Gonnet +4
We perform simulations of giant impacts onto the young Uranus using smoothed particle hydrodynamics (SPH) with over 100 million particles. This 100--1000 improvement in par…
Image Reconstruction Techniques in Neutron and Gamma-Ray Spectroscopy: Improving Lunar Prospector Data
Jack T. Wilson, David J. Lawrence, Patrick N. Peplowski +4
We present improved resolution maps of the Lunar Prospector Neutron Spectrometer thermal, epithermal and fast neutron data and Gamma-Ray Spectrometer Th-line fluxes via global appl…
Evidence for a Localised Source of the Argon in the Lunar Exosphere
Jacob A. Kegerreis, Vincent R. Eke, Richard J. Massey +3
We perform the first tests of various proposed explanations for observed features of the Moon's argon exosphere, including models of: spatially varying surface interactions; a sour…
Evidence for explosive silicic volcanism on the Moon from the extended distribution of thorium near the Compton-Belkovich Volcanic Complex
J. T. Wilson, V. R. Eke, R. J. Massey +6
We reconstruct the abundance of thorium near the Compton-Belkovich Volcanic Complex on the Moon, using data from the Lunar Prospector Gamma Ray Spectrometer. We enhance the resolut…
Extragalactic number counts at 100 um, free from cosmic variance
B. Sibthorpe, R. Ivison, R. J. Massey +4
We use data from the Disc Emission via a Bias-free Reconnaissance in the Infrared/Submillimetre (DEBRIS) survey, taken at 100 um with the Photoconductor Array Camera and Spectromet…
