We perform a suite of smoothed particle hydrodynamics simulations to investigate in detail the results of a giant impact on the young Uranus. We study the internal structure, rotation rate, and atmospheric retention of the post-impact planet, as well as the composition of material ejected into orbit. Most of the material from the impactor's rocky core falls in to the core of the target. However, for higher angular momentum impacts, significant amounts become embedded anisotropically as lumps in… 
The Exchange of Mass and Angular Momentum in the Impact Event of Ice Giant Planets: Implications for the Origin of Uranus
Uranus has a tilted rotation axis, which is supposed to be caused by a giant impact. In general, an impact event also changes the internal compositional distribution and drives mass ejection from the
Planetary giant impacts: convergence of high-resolution simulations using efficient spherical initial conditions and swift
We perform simulations of giant impacts on to the young Uranus using smoothed particle hydrodynamics (SPH) with over 100 million particles. This 100–1000 × improvement in particle number reveals
Can the Uranian Satellites Form from a Debris Disk Generated by a Giant Impact?
Hydrodynamic simulations of a giant impact to proto-Uranus indicated that such an impact could tilt its rotational axis and produce a circumplanetary debris disk beyond the corotation radius of
Scaling laws for the geometry of an impact-induced magma ocean
Bifurcation in the history of Uranus and Neptune: the role of giant impacts
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 accretion from a disc,
Uranian satellite formation by evolution of a water vapour disk generated by a giant impact
The ice-giant planet Uranus probably underwent a giant impact, given that its spin axis is tilted by 98 degrees 1 – 3 . That its satellite system is equally inclined and prograde suggests that it was
Coaccretion + Giant-impact Origin of the Uranus System: Tilting Impact
The origin of the Uranian satellite system remains uncertain. The four major satellites have nearly circular, coplanar orbits, and the ratio of the satellite system to planetary mass resembles
Atmosphere loss in planet–planet collisions
Many of the planets discovered by the Kepler satellite are close orbiting super-Earths or mini-Neptunes. Such objects exhibit a wide spread of densities for similar masses. One possible explanation
Tilting Ice Giants with a Spin–Orbit Resonance
Giant collisions can account for Uranus's and Neptune's large obliquities, yet generating two planets with widely different tilts and strikingly similar spin rates is a low-probability event.

Embryo impacts and gas giant mergers – II. Diversity of hot Jupiters’ internal structure
We consider the origin of compact, short-period, Jupiter-mass planets. We propose that their diverse structure is caused by giant impacts of embryos and super-Earths or mergers with other gas giants

Mini-Neptunes and volatile-poor super-Earths coexist on adjacent orbits in proximity to host stars such as Kepler-36 and Kepler-11. Several post-formation processes have been proposed for explaining

We present high-resolution, three-dimensional simulations using a smooth particle hydrodynamics (SPH) code of giant impacts involving young Jupiter-like planets. Our aim is to explore the effect of
Convective-region geometry as the cause of Uranus' and Neptune's unusual magnetic fields
Three-dimensional numerical dynamo simulations that model the dynamo source region as a convecting thin shell surrounding a stably stratified fluid interior produce magnetic fields similar in morphology to those of Uranus and Neptune.

Hydrodynamical simulations of rotating disk play important roles in the field of astrophysical and planetary science. Smoothed Particle Hydrodynamics (SPH) has been widely used for such simulations.
