Capture of interstellar objects during stellar encounters
Sean N. Raymond, Nathan A. Kaib, Matthew J. Hopkins
As they orbit within the Galaxy, stars swim through a vast population of interstellar objects (ISOs). In this paper, we use N-body simulations to show that a fraction of ISOs withi…
A Potential Signature of HD 7977's Passage Among Observed Long-Period Comet Orbits
Nathan A. Kaib, Sean N. Raymond
It is generally presumed that the tidal field of the Milky Way's disk is the main perturbation that has driven observed long-period comets (LPCs) from the Oort cloud into the inner…
The fragility of the Uranian moons during the giant planet instability
Matthew S. Clement, Nathan A. Kaib, Andre Izidoro +1
It is thought that, sometime after their formation, the solar system's giant planets experienced a dynamical instability that caused their orbits to excite, diverge, and ejected on…
Was the Solar System's dynamical instability triggered by a (sub)stellar flyby?
Sean N. Raymond, Nathan A. Kaib
An instability among the giant planets' orbits can match many aspects of the Solar System's current orbital architecture. We explore the possibility that this dynamical instability…
Evaluating an Embryo Origin for Detached TNOs within Full Kuiper Belt Formation Models
Nathan A. Kaib, Chadwick A. Trujillo, Scott S. Sheppard
With perihelia well beyond Neptune, but semimajor axes and eccentricities indicative of substantial perturbation, the origins of detached trans-Neptunian objects (TNOs) remain a dy…
Very-wide-orbit planets from dynamical instabilities during the stellar birth cluster phase
André Izidoro, Sean N. Raymond, Nathan A. Kaib +2
Gas giant planets have been detected on eccentric orbits several hundreds of astronomical units in size around other stars. It has been proposed that even the Sun hosts a wide-orbi…
