Secular Behavior of Exoplanets: Self-Consistency and Comparisons with the Planet-Planet Scattering Hypothesis
Miles Timpe, Rory Barnes, Ravikumar Kopparapu +3
If mutual gravitational scattering among exoplanets occurs, then it may produce unique orbital properties. For example, two-planet systems that lie near the boundary between circul…
APOSTLE: Longterm Transit Monitoring and Stability Analysis of XO-2b
Praveen Kundurthy, Rory Barnes, Andrew C. Becker +4
The Apache Point Survey of Transit Lightcurves of Exoplanets (APOSTLE) observed 10 transits of XO-2b over a period of three years. We present measurements which confirm previous es…
Planet-planet scattering in planetesimal disks II: Predictions for outer extrasolar planetary systems
Sean N. Raymond, Philip J. Armitage, Noel Gorelick
We develop an idealized dynamical model to predict the typical properties of outer extrasolar planetary systems, at radii beyond 5 AU. Our hypothesis is that dynamical evolution in…
Planet-planet scattering leads to tightly packed planetary systems
Sean N. Raymond, Rory Barnes, Dimitri Veras +3
The known extrasolar multiple-planet systems share a surprising dynamical attribute: they cluster just beyond the Hill stability boundary. Here we show that the planet-planet scatt…
