Journal ArticleDOI
Origin of the Moon in a giant impact near the end of the Earth's formation.
Robin M. Canup,Erik Asphaug +1 more
TL;DR: This work reports a class of impacts that yield an iron-poor Moon, as well as the current masses and angular momentum of the Earth–Moon system, and suggests that the Moon formed near the very end of Earth's accumulation.
Journal ArticleDOI
Catastrophic Disruptions Revisited
Willy Benz,Erik Asphaug +1 more
TL;DR: In this article, the authors used a smooth particle hydrodynamics method to simulate colliding rocky and icy bodies from centimeter scale to hundreds of kilometers in diameter in an effort to define self-consistently the threshold for catastrophic disruption.
Journal ArticleDOI
Detection of Water in the LCROSS Ejecta Plume
Anthony Colaprete,Peter H. Schultz,Jennifer L. Heldmann,Diane H. Wooden,Mark Shirley,Kimberly Ennico,Brendan Hermalyn,William Marshall,William Marshall,Antonio J. Ricco,Richard C. Elphic,David Goldstein,D. Summy,G. D. Bart,Erik Asphaug,Don Korycansky,David Landis,Luke Sollitt +17 more
TL;DR: The Lunar Crater Observation and Sensing Satellite (LCROSS) mission was designed to provide direct evidence that water ice may be presented in permanently shadowed craters of the Moon, and spectral bands of a number of other volatile compounds were observed.
Journal ArticleDOI
Simulations of brittle solids using smooth particle hydrodynamics
Willy Benz,Erik Asphaug +1 more
TL;DR: In this article, a version of the smooth particle hydrodynamics (SPH) method suitable for modeling solids is described, which includes strength and implements a von Mises yielding relation for stresses beyond the Hugoniot elastic limit.
Journal ArticleDOI
Hit-and-run planetary collisions
TL;DR: It is shown that colliding planets do not simply merge, as is commonly assumed, and in many cases, the smaller planet escapes from the collision highly deformed, spun up, depressurized from equilibrium, stripped of its outer layers, and sometimes pulled apart into a chain of diverse objects.
