A system of two small planets orbiting the Sun on low-eccentricity, low-inclination orbits is stable with respect to close encounters if the initial semi-major axis difference, Δ, measured in mutual Hill radii,RH, exceeds[formula], due to conservation of energy and angular momentum. We investigate the stability of systems of more than two planets using numerical integrations. We find that systems with Δ 10 are also unstable. The slopebdepends weakly on the number of planets, but is independent… Expand
Eccentricities and the stability of closely-spaced five-planet systems
Observations of exoplanets have revealed that systems with planets on closely-spaced orbits are common, which motivates the question "How closely can planets orbit to one another and still beExpand
Orbital stability of compact three-planet systems, I: Dependence of system lifetimes on initial orbital separations and longitudes
We explore the orbital dynamics of systems consisting of three planets, each as massive as the Earth, on coplanar, initially circular, orbits about a star of one solar mass. The initial semimajorExpand
The influence of inclinations on the dynamical stability of multi-planet systems
A type of compactly spaced and comparably sized multi-exoplanet system similar to TRAPPIST-1 has been discovered recently. The stability of these systems is an important issue, requiring furtherExpand
Predicting Planets in Kepler Multi-Planet Systems
We investigate whether any multi-planet systems among Kepler candidates (2011 February release) can harbor additional terrestrial-mass planets or smaller bodies. We apply the "packed planetaryExpand
Scattering Outcomes of Close-in Planets: Constraints on Planet Migration
Many exoplanets in close-in orbits are observed to have relatively high eccentricities and large stellar obliquities. We explore the possibility that these result from planet-planet scattering byExpand
Spacing of Kepler Planets: Sculpting by Dynamical Instability
We study the orbital architecture of multi-planet systems detected by the Kepler transit mission using N-body simulations, focusing on the orbital spacing between adjacent planets in systems showingExpand
The stability of ultra-compact planetary systems
Aims. We investigate the dynamical stability of compact planetary systems in the CoRoT discovery space, i.e., with orbital periods of less than 50 days, including a detailed study of the stability ofExpand
Effects of non-Kozai mutual inclinations on two-planet system stability through all phases of stellar evolution
Previous full-lifetime simulations of single-star multi-planet systems across all phases of stellar evolution have predominately assumed coplanar or nearly coplanar orbits. Here we assess theExpand
Orbital Stability of Multi-Planet Systems: Behavior at High Masses
In the coming years, high contrast imaging surveys are expected to reveal the characteristics of the population of wide-orbit, massive, exoplanets. To date, a handful of wide planetary massExpand
Dynamical Stability of Earth-like Planetary Orbits in Binary Systems
This paper explores the stability of an Earth-like planet orbiting a solar-mass star in the presence of an outer-lying intermediate-mass companion. The overall goal is to estimate the fraction ofExpand
