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…

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…

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…
