A hit-and-run giant impact scenario
Abstract The formation of the Moon from the debris of a slow and grazing giant impact of a Mars-sized impactor on the proto-Earth ( Cameron and Ward [1976] . Lunar Planet. Sci. Conf.; Canup andExpand

The relativistic electron response at geosynchronous orbit during the January 1997 magnetic storm
The first geomagnetic storm of 1997 began on January 10. It is of particular interest because it was exceptionally well observed by the full complement of International Solar Terrestrial PhysicsExpand

Nickel isotopes in iron meteorites–nucleosynthetic anomalies in sulphides with no effects in metals and no trace of 60Fe
Iron-60 decays to 60Ni with a half-life of 1.49 Myrs such that Ni isotopic studies of iron meteorites have the potential to provide powerful new constraints on the energy budgets and time-scales ofExpand

Cosmogenic nuclides in Almahata Sitta ureilites: Cosmic-ray exposure age, preatmospheric mass, and bulk density of asteroid 2008 TC3
Abstract– On October 7, 2008, a small F-class asteroid, 2008 TC3, exploded in Earth’s atmosphere, and produced a strewn field of meteorites in the Nubian Desert of Sudan. Subsequent searches yieldedExpand

Interstellar residence times of presolar SiC dust grains from the murchison carbonaceous meteorite
The time span between the formation of presolar grains in stellar outflows and their incorporation into early solar-system solids is poorly constrained. Knowledge of this time span is essential for aExpand

On the origin and composition of Theia: Constraints from new models of the Giant Impact
Abstract Knowing the isotopic composition of Theia, the proto-planet which collided with the Earth in the Giant Impact that formed the Moon, could provide interesting insights on the state ofExpand

Determining the impactor of the Ordovician Lockne crater: Oxygen and neon isotopes in chromite versus sedimentary PGE signatures
Abundant chromite grains with L-chondritic composition in the resurge deposits of the Lockne impact crater (458 Myr old: dia. similar to 10 km) in Sweden have been inferred to represent relictExpand

Noble gases in 18 Martian meteorites and angrite Northwest Africa 7812—Exposure ages, trapped gases, and a re‐evaluation of the evidence for solar cosmic ray‐produced neon in shergottites and other
We present noble gas data for 16 shergottites, 2 nakhlites (NWA 5790, NWA 10153), and 1 angrite (NWA 7812). Noble gas exposure ages of the shergottites fall in the 1–6 Ma range found in previousExpand

A tale of clusters: no resolvable periodicity in the terrestrial impact cratering record
Rampino & Caldeira (2015) carry out a circular spectral analysis (CSA) of the terrestrial impact cratering record over the past 260 million years (Ma), and suggest a ~26 Ma periodicity of impactExpand
