A Formation-Stage Bottleneck for Exomoons around Close-in Rocky Planets
Rongxi Bi, Hongping Deng, Christian Reinhardt +2
Massive moons around rocky exoplanets are expected outcomes of giant impacts, yet no exomoon has been securely confirmed. We address this problem using meshless finite-mass simulat…
Smoothed Particle Hydrodynamics in pkdgrav3 for Shock Physics Simulations. II. Shear Strength
Thomas Meier, Christian Reinhardt, Martin Jutzi +2
Material strength effects have been recently shown to be significant in giant impacts even at scales of planetary collisions. Despite this, their effects are often neglected in num…
Smoothed Particle Hydrodynamics in pkdgrav3 for Shock Physics Simulations. I. Hydrodynamics
Thomas Meier, Douglas Potter, Christian Reinhardt +1
We present pkdgrav3, a high-performance, fully parallel tree-SPH code designed for large-scale hydrodynamic simulations including self-gravity. Building upon the long development h…
A scaling relation for core heating by giant impacts and implications for dynamo onset
You Zhou, Peter E. Driscoll, Mingming Zhang +2
Accretional heating of Earth's interior during formation is pivotal to its subsequent thermal and chemical evolution. In particular, impact heating of Earth's core is expected, but…
Giant Planet Formation by Disk Instability
Ravit Helled, Oliver Schib, Christian Reinhardt +4
The disk instability (DI) model for giant planet formation remains an attractive alternative in explaining the formation of giant planets at early times, giant planets at large rad…
Recent advances in modelling of global-scale collisions using smoothed particle hydrodynamics
Christian Reinhardt, Sabina D. Raducan, Thomas Meier +3
Impacts play a fundamental role in shaping the physical and chemical properties of the objects in our Solar System. Given the challenges in replicating such collisions through labo…
