Making the Moon from a Fast-Spinning Earth: A Giant Impact Followed by Resonant Despinning
TLDR
Computer simulations show that a giant impact on early Earth could lead to a Moon with a composition similar to Earth’s, and shows that a faster-spinning early Earth-Moon system can lose angular momentum and reach the present state through an orbital resonance between the Sun and Moon. Expand
COLLISIONS BETWEEN GRAVITY-DOMINATED BODIES. I. OUTCOME REGIMES AND SCALING LAWS
Collisions are the core agent of planet formation. In this work, we derive an analytic description of the dynamical outcome for any collision between gravity-dominated bodies. We conductExpand
Velocity-Dependent Catastrophic Disruption Criteria for Planetesimals
The resistance of planetesimals to collisional erosion changes dramatically during planet formation. The transition between accretion and erosion from a collision is defined by the relationshipExpand
Full numerical simulations of catastrophic small body collisions
Abstract The outcome of collisions between small icy bodies, such as Kuiper belt objects, is poorly understood and yet a critical component of the evolution of the trans-neptunian region. TheExpand
Records of an ancient Martian magnetic field in ALH84001
Although Mars does not presently appear to have a global dynamo magnetic field, strong crustal fields have recently been detected by the Mars Global Surveyor above surfaces formed ∼3 or more Ga. WeExpand
The Formation of the Collisional Family Around the Dwarf Planet Haumea
Haumea, a rapidly rotating elongated dwarf planet ({approx}1500 km in diameter), has two satellites and is associated with a 'family' of several smaller Kuiper Belt objects (KBOs) in similar orbits.Expand
Collisional Stripping and Disruption of Super-Earths
The final stage of planet formation is dominated by collisions between planetary embryos. The dynamics of this stage determine the orbital configuration and the mass and composition of planets in theExpand
Geology of Lonar Crater, India
Lonar Crater, India, is one of the youngest and best preserved impact structures on Earth. The 1.88-km-diameter simple crater formed entirely within the Deccan traps, making it a useful analogue forExpand
COLLISIONS BETWEEN GRAVITY-DOMINATED BODIES. II. THE DIVERSITY OF IMPACT OUTCOMES DURING THE END STAGE OF PLANET FORMATION
Numerical simulations of the stochastic end stage of planet formation typically begin with a population of embryos and planetesimals that grow into planets by merging. We analyzed the impactExpand
Evolution and persistence of 5‐μm hot spots at the Galileo probe entry latitude
We present a study on the longitudinal locations, morphology, and evolution of the 5-μm hot spots at 6.5°N latitude (planetocentric) from an extensive Infrared Telescope Facility-National ScienceExpand
