Astrophysical Journal, 2012 A model of coupled mantle convection and planetary tectonics is used to demonstrate that history dependence can outweigh the effects of a planet's energy content and material parameters in determining its tectonic state. The mantle convection-surface tectonics system allows multiple tectonic modes to exist for equivalent planetary parameter values. The

Impact bombardment of the terrestrial planets and the early history of the Solar System
Nature Geoscience, 2013About 4 billion years ago, the terrestrial planets were bombarded by asteroids following an orbital shake-up of the outer Solar System. Lunar samples, planetary cratering records and dynamical models piece together an increasingly coherent view of this bombardment interval.

Orbital stability of massive protoplanets in the terrestrial planet region of the solar system
The Moon and the Planets, 1978 A number of theories of the formation of the planets advocate that the terrestrial planets were originally of cosmic composition and that it is only subsequent evolution that has removed their volatile components. This paper shows that such protoplanets could have remained in the terrestrial planet region without significant changes occurring in their ...

, 1982 The ancient impact record of the terrestrial-type planets Mercury, Mars, earth’s moon, and of the satellites of Jupiter and Saturn is discussed on the basis of data from spacecraft imagery. The mass-velocity distribution of the impactors seems to have been the same or very similar in the inner part of the solar system and probably also at Jupiter and ...

Red terrestrial planets: Searching for evidence for life beyond the Solar System
, 2020 Red dwarfs, which are stars that are typically born with masses below 0.6 Msun, are the most numerous stars and comprise about 70% of the stellar population in the Solar neighbourhood. Since we rely on indirect methods for detection of exoplanets, this small stars provide a number of advantages for the detection of the smallest planets.

A Postulated Planetary Collision, the Terrestrial Planets, the Moon and Smaller Solar-System Bodies
Earth, Moon, and Planets, 2013In a scenario produced by the Capture Theory of planetary formation, a collision between erstwhile solar-system giant planets, of masses 798.75 and 598.37 M⊕, is simulated using smoothed-particle hydrodynamics. Due to grain-surface chemistry that takes place in star-forming clouds, molecular species containing hydrogen, with a high D/H ratio taken as 0.

A new terrestrial planet formation model (Walsh et al., this meeting) explores the effects of a two-stage, inward-then-outward migration of Jupiter and Saturn, as found in numerous hydrodynamical simulations of giant planet formation (Masset & Snellgrove 2001, Morbidelli & Crida 2007, Pierens & Nelson 2008). Walsh et al.
