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 compact systems sometimes contain multiple transiting planets, so that their orbital angular momentum vectors are tightly aligned. Since planetary orbits are susceptible to forced oscillations of their inclination angles, the highly aligned nature of these systems places constraints on possible…

Worlds without Moons: Exomoon Constraints for Compact Planetary Systems

One of the primary surprises of exoplanet detections has been the discovery of compact planetary systems, whereby numerous planets reside within ∼0.5 au of the host star. Many of these kinds of

Current observations indicate that the planet formation process often produces multiple planet systems with nearly circular orbits, regular spacing, a narrow range of inclination angles, and

On the origin of the eccentricity dichotomy displayed by compact super-Earths: dynamical heating by cold giants

Approximately half of the planets discovered by NASA's Kepler mission are in systems where just a single planet transits its host star, and the remaining planets are observed to be in multi-planet

Exterior Companions to Hot Jupiters Orbiting Cool Stars Are Coplanar

The existence of hot Jupiters has challenged theories of planetary formation since the first extrasolar planets were detected. Giant planets are generally believed to form far from their host stars,

Dynamical Constraints on Nontransiting Planets Orbiting TRAPPIST-1

We derive lower bounds on the orbital distance and inclination of a putative planet beyond the transiting seven planets of TRAPPIST-1, for a range of masses ranging from 0.08 MJup to 3.5 MJup. While

The Origin of Systems of Tightly Packed Inner Planets with Misaligned, Ultra-short-period Companions

Ultra-short-period planets provide a window into the inner edge of the parameter space occupied by planetary orbits. In one particularly intriguing class of multiplanet systems, the

Relativistic Dynamical Stability Criterion of Multiplanet Systems with a Distant Companion

Multiplanetary systems are prevalent in our Galaxy. The long-term stability of such systems may be disrupted if a distant inclined companion excites the eccentricity and inclination of the inner

Hidden planetary friends: on the stability of two-planet systems in the presence of a distant, inclined companion

Recent observational campaigns have shown that multi-planet systems seem to be abundant in our Galaxy. Moreover, it seems that these systems might have distant companions, either planets,

Recent observations have indicated a strong connection between compact (a ≲ 0.5 au) super-Earth and mini-Neptune systems and their outer (a ≳ a few au) giant planet companions. We study the

Eccentricities and inclinations of multiplanet systems with external perturbers

Compact multi-planet systems containing super-Earths or sub-Neptunes, commonly found around solar-type stars, may be surrounded by external giant planet or stellar companions, which can shape the



Oscillations of relative inclination angles in compact extrasolar planetary systems

The Kepler Mission has detected dozens of compact planetary systems with more than four transiting planets. This sample provides a collection of close-packed planetary systems with relatively little

Perturbation of Compact Planetary Systems by Distant Giant Planets

We examine the effect of secular perturbations by giant planets on systems of multiple, lower mass planets orbiting Sun-like stars. We simulate the effects of forcing both eccentricity and

The effects of external planets on inner systems: multiplicities, inclinations and pathways to eccentric warm Jupiters

We study how close-in systems such as those detected by Kepler are affected by the dynamics of bodies in the outer system. We consider two scenarios: outer systems of giant planets potentially


Eighty planetary systems of two or more planets are known to orbit stars other than the Sun. For most, the data can be sufficiently explained by non-interacting Keplerian orbits, so the dynamical

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 showing

A closely packed system of low-mass, low-density planets transiting Kepler-11

Kepler spacecraft observations of a single Sun-like star are reported that reveal six transiting planets, five with orbital periods between 10 and 47 days and a sixth planet with a longer period, among the smallest for which mass and size have both been measured.

Outer-planet scattering can gently tilt an inner planetary system

Chaotic dynamics are expected during and after planet formation, and a leading mechanism to explain large eccentricities of gas giant exoplanets is planet-planet gravitational scattering. The same


The Kepler mission has detected thousands of planetary systems with one to seven transiting planets packed within 0.7 au from their host stars. There is an apparent excess of single-transit planet

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


Jupiter and Saturn play host to an impressive array of satellites, making it reasonable to suspect that similar systems of moons might exist around giant extrasolar planets. Furthermore, a
