The Kepler mission results indicate that systems of tightly packed inner planets (STIPs) are present around of order 5% of FGK field stars (whose median age is ∼5 Gyr). We propose that STIPs initially surrounded nearly all such stars, and those observed are the final survivors of a process in which long-term metastability eventually ceases and the systems proceed to collisional consolidation or destruction, losing roughly equal fractions of systems every decade in time. In this context, we also…

We propose that two of the most surprising results so far among exoplanet discoveries are related: the existences of both hot Jupiters and the high frequency of multi-planet systems with periods P ≲
Dynamical Avenues for Mercury’s Origin. II. In Situ Formation in the Inner Terrestrial Disk
Modern terrestrial-planet formation models are highly successful at consistently generating planets with masses and orbits analogous to those of Earth and Venus. In stark contrast to classic
The Exoplanet Population Observation Simulator. I. The Inner Edges of Planetary Systems
The Kepler survey provides a statistical census of planetary systems out to the habitable zone. Because most planets are non-transiting, orbital architectures are best estimated using simulated
Prospects for detecting decreasing exoplanet frequency with main-sequence age using PLATO
The space mission PLATO will usher in a new era of exoplanetary science by expanding our current inventory of transiting systems and constraining host star ages, which are currently highly uncertain.
Lifetime Against Sublimation and an Initial Mass Estimate for the Exoplanet α Centauri Bb
A two-component, core-mantle, model is developed to estimate the lifetime against destruction via sublimation of close-orbit, terrestrial-mass exoplanets. We specifically focus on the nearest
Dynamically Hot Super-Earths from Outer Giant Planet Scattering
The hundreds of multiple planetary systems discovered by the Kepler mission are typically observed to reside in close-in ( AU), low-eccentricity, low-inclination orbits. We run N-body experiments to
Formation of Terrestrial Planets
The past decade has seen major progress in our understanding of terrestrial planet formation. Yet key questions remain. In this review we first address the growth of 100 km-scale planetesimals as a
Effects of unseen additional planetary perturbers on compact extrasolar planetary systems
Motivated by the large number of compact extrasolar planetary systems discovered by the Kepler Mission, this paper considers perturbations due to possible additional outer planets. The discovered
How Close are Compact Multiplanet Systems to the Stability Limit?
Transit surveys have revealed a significant population of compact multiplanet systems, containing several sub-Neptune–mass planets on close-in, tightly-packed orbits. These systems are thought to
We reconsider the commonly held assumption that warm debris disks are tracers of terrestrial planet formation. The high occurrence rate inferred for Earth-mass planets around mature solar-type stars


Origin of the cataclysmic Late Heavy Bombardment period of the terrestrial planets
This model not only naturally explains the Late Heavy Bombardment, but also reproduces the observational constraints of the outer Solar System.
Rapid disappearance of a warm, dusty circumstellar disk
Observations of a young, Sun-like star where infrared flux from post-collisional ejecta has decreased drastically, by a factor of about 30, over a period of less than two years are reported.
Rapid Dynamical Chaos In An Exoplanetary System
We report on the long-term dynamical evolution of the two-planet Kepler-36 system, which consists of a super-Earth and a sub-Neptune in a tightly packed orbital configuration. The orbits of the
Chaotic Disintegration of the Inner Solar System
On timescales that greatly exceed an orbital period, typical planetary orbits evolve in a stochastic yet stable fashion. On even longer timescales, however, planetary orbits can spontaneously
Mercurian impact ejecta: Meteorites and mantle
Abstract— We have examined the fate of impact ejecta liberated from the surface of Mercury due to impacts by comets or asteroids, in order to study 1) meteorite transfer to Earth, and 2)
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 the
Hit-and-run planetary collisions
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.
Iron meteorites as remnants of planetesimals formed in the terrestrial planet region
It is shown that the iron-meteorite parent bodies most probably formed in the terrestrial planet region, and it is predicted that some asteroids are main-belt interlopers and a select few may even be remnants of the long-lost precursor material that formed the Earth.
Existence of collisional trajectories of Mercury, Mars and Venus with the Earth
Numerical simulations of the evolution of the Solar System over 5 Gyr, including contributions from the Moon and general relativity find that one per cent of the solutions lead to a large increase in Mercury’s eccentricity—an increase large enough to allow collisions with Venus or the Sun.
Can planetary instability explain the Kepler dichotomy
The planet candidates discovered by the Kepler mission provide a rich sample to constrain the architectures and relative inclinations of planetary systems within approximately 0.5 AU of their host
