A systematic survey of Moon-forming giant impacts: Non-rotating bodies

Miles Timpe, Christian Reinhardt, Thomas Meier +2

In the leading theory of lunar formation, known as the giant impact hypothesis, a collision between two planet-size objects resulted in a young Earth surrounded by a circumplanetar…

Forming Iron-rich Planets with Giant Impacts

Christian Reinhardt, Thomas Meier, Joachim Stadel +2

We investigate mantle stripping giant impacts (GI) between super-Earths with masses between 1 M and 20 M. We infer new scaling laws for the mass of the larges…

The EOS/Resolution Conspiracy: Convergence in Proto-Planetary Collision Simulations

Thomas Meier, Christian Reinhardt, Joachim Stadel

We investigate how the choice of equation of state (EOS) and resolution conspire to affect the outcomes of giant impact (GI) simulations. We focus on the simple case of equal mass…

Did Uranus' regular moons form via a rocky giant impactor?

Jason Man Yin Woo, Christian Reinhardt, Marco Cilibrasi +3

The formation of Uranus' regular moons has been suggested to be linked to the origin of its enormous spin axial tilt (~98^o). A giant impact between proto-Uranus and a 2-3 M_Earth…

Could Uranus and Neptune form by collisions of planetary embryos?

Alice Chau, Christian Reinhardt, André Izidoro +2

The origin of Uranus and Neptune remains a challenge for planet formation models. A potential explanation is that the planets formed from a population of a few planetary embryos wi…

Bifurcation in the history of Uranus and Neptune: the role of giant impacts

Christian Reinhardt, Alice Chau, Joachim Stadel +1

Despite many similarities, there are significant observed differences between Uranus and Neptune: while Uranus is tilted and has a regular set of satellites, suggesting their accre…

Primordial Earth mantle heterogeneity caused by the Moon-forming giant impact

Hongping Deng, Maxim D. Ballmer, Christian Reinhardt +4

The giant impact hypothesis for Moon formation successfully explains the dynamic properties of the Earth-Moon system but remains challenged by the similarity of isotopic fingerprin…

A special giant impact model: implications on core-mantle chemical differentiation

You Zhou, Christian Reinhardt, Hongping Deng +2

The Earths core formation process has decisive effect in the chemical differentiation between the Earths core and its mantle. Here, we propose a new core formation model which is c…

Forming Mercury by Giant Impacts

Alice Chau, Christian Reinhardt, Ravit Helled +1

The origin of Mercury's high iron-to-rock ratio is still unknown. In this work we investigate Mercury's formation via giant impacts and consider the possibilities of a single giant…

Enhanced mixing in giant impact simulations with a new Lagrangian method

Hongping Deng, Christian Reinhardt, Federico Benitez +2

Giant impacts (GIs) are common in the late stage of planet formation. The Smoothed Particle Hydrodynamics (SPH) method is widely used for simulating the outcome of such violent col…

Numerical aspects of Giant Impact simulations

Christian Reinhardt, Joachim Stadel

In this paper we present solutions to three short comings of Smoothed Particles Hydrodynamics (SPH) encountered in previous work when applying it to Giant Impacts. First we introdu…

Fourier-Taylor Parameterization of Unstable Manifolds for Parabolic Partial Differential Equations: Formalization, Implementation, and Rigorous Validation

Jason Mireles-James, Christian Reinhardt

In this paper we study high order expansions of chart maps for local finite dimensional unstable manifolds of hyperbolic equilibrium solutions of scalar parabolic partial different…
