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…
