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…
Origin of Mars's moons by disruptive partial capture of an asteroid
Jacob A. Kegerreis, Jack J. Lissauer, Vincent R. Eke +2
The origin of Mars's small moons, Phobos and Deimos, remains unknown. They are typically thought either to be captured asteroids or to have accreted from a debris disk produced by…
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…
SWIFT: A modern highly-parallel gravity and smoothed particle hydrodynamics solver for astrophysical and cosmological applications
Matthieu Schaller, Josh Borrow, Peter W. Draper +24
Numerical simulations have become one of the key tools used by theorists in all the fields of astrophysics and cosmology. The development of modern tools that target the largest ex…
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…
