Motivated by the report of a possible new planetary member of the Solar System, this work calculates cross sections for interactions between passing stars and this proposed Planet Nine. Evidence for the new planet is provided by the orbital alignment of Kuiper Belt objects, and other Solar System properties, which suggest a Neptune-mass object on an eccentric orbit with semimajor axis $a_9\approx400-1500$ AU. With such a wide orbit, Planet Nine has a large interaction cross section, and is… Expand

Evaluating the Dynamical Stability of Outer Solar System Objects in the Presence of Planet Nine
We evaluate the dynamical stability of a selection of outer solar system objects in the presence of the proposed new Solar System member Planet Nine. We use a Monte Carlo suite of numerical N-bodyExpand
The fates of Solar system analogues with one additional distant planet
The potential existence of a distant planet (“Planet Nine”) in the Solar system has prompted a re-think about the evolution of planetary systems. As the Sun transitions from a main sequence star intoExpand
Circularizing Planet Nine through dynamical friction with an extended, cold planetesimal belt
Unexpected clustering in the orbital elements of minor bodies beyond the Kuiper belt has led to speculations that our Solar system actually hosts nine planets, the eight established plus aExpand
Is there an exoplanet in the Solar System
We investigate the prospects for the capture of the proposed Planet 9 from other stars in the Sun's birth cluster. Any capture scenario must satisfy three conditions: the encounter must be moreExpand
Stellar Flybys Interrupting Planet–Planet Scattering Generates Oort Planets
Wide-orbit exoplanets are starting to be detected, and planetary formation models are under development to understand their properties. We propose a population of "Oort" planets around other stars,Expand
Constraints on Planet Nine’s Orbit and Sky Position within a Framework of Mean-motion Resonances
A number of authors have proposed that the statistically significant orbital alignment of the most distant Kuiper Belt Objects (KBOs) is evidence of an as-yet undetected planet in the outer solarExpand
Making Planet Nine: A Scattered Giant in the Outer Solar System
Correlations in the orbits of several minor planets in the outer solar system suggest the presence of a remote, massive Planet Nine. With at least ten times the mass of the Earth and a perihelionExpand
The Generation of the Distant Kuiper Belt by Planet Nine from an Initially Broad Perihelion Distribution
The observation that the orbits of long-period Kuiper Belt objects are anomalously clustered in physical space has recently prompted the Planet Nine hypothesis - the proposed existence of a distantExpand
CONSEQUENCES of A DISTANT MASSIVE PLANET on the LARGE SEMIMAJOR AXIS TRANS-NEPTUNIAN OBJECTS
We explore the distant giant planet hypothesis by integrating the large semi-major axis, large pericenter Trans-Neptunian Objects (TNOs) in the presence of the giant planets and an external perturberExpand
Fly-by encounters between two planetary systems I: Solar system analogues
Stars formed in clusters can encounter other stars at close distances. In typical open clusters in the Solar neighbourhood containing hundreds or thousands of member stars, 10–20 per cent ofExpand

Abstract This paper explores the intermediate-time dynamics of newly formed solar systems with a focus on possible mechanisms for planetary migration. We consider two limiting corners of theExpand

Close encounters in young stellar clusters: implications for planetary systems in the solar neighbourhood
TLDR
Dynamical encounters in young stellar clusters may produce at least some of the extrasolar planetary systems observed in the solar neighbourhood, beginning with a population of planetary systems exactly resembling the Solar System around single stars. Expand
The effects of fly‐bys on planetary systems
Most of the observed extrasolar planets are found on tight and often eccentric orbits. The high eccentricities are not easily explained by planet-formation models, which predict that planets shouldExpand
A Sedna-like body with a perihelion of 80 astronomical units
TLDR
The detection of 2012 VP113 confirms that Sedna is not an isolated object; instead, both bodies may be members of the inner Oort cloud, whose objects could outnumber all other dynamically stable populations in the Solar System. Expand
