Planets are thought to form via accretion from a remnant disk of gas and solids around a newly formed star. During this process material in the disk either remains bound to the star as part of either a planet, a smaller celestial body, or makes up part of the interplanetary medium; falls into the star; or is ejected from the system. Herein we use dynamical models to probe the abundance and properties of ejected material during late-stage planet formation and estimate their contribution to the…

No large population of unbound or wide-orbit Jupiter-mass planets
A sample of microlensing events six times larger than that of ref. 11 is analysed, finding no excess of events with timescales in this range, with a 95 per cent upper limit on the frequency of Jupiter-mass free-floating or wide-orbit planets of 0.25 planets per main-sequence star.
On the Origin of Free-Floating Planets Planet Ejection During Terrestrial Planet Formation
During the formation of terrestrial planets, many planetesimals and planetary embryos may be ejected from the formation region. As the dynamics of these objects are affected by the perturbation of
On the origin of free-floating planets: The effect of planet migration
Many free-floating planets have been detected through the microlensing technique, however very little has been done to determine their origins. In this study, we explored the possibility that planets
Implications of the interstellar object 1I/'Oumuamua for planetary dynamics and planetesimal formation
'Oumuamua, the first bona-fide interstellar planetesimal, was discovered passing through our Solar System on a hyperbolic orbit. This object was likely dynamically ejected from an extrasolar
Two new free-floating or wide-orbit planets from microlensing
Planet formation theories predict the existence of free-floating planets that have been ejected from their parent systems. Although they emit little or no light, they can be detected during
Habitable Evaporated Cores and the Occurrence of Panspermia near the Galactic Center
Black holes growing via the accretion of gas emit radiation that can photoevaporate the atmospheres of nearby planets. Here we couple planetary structural evolution models of sub-Neptune mass planets
A Terrestrial-mass Rogue Planet Candidate Detected in the Shortest-timescale Microlensing Event
Some low-mass planets are expected to be ejected from their parent planetary systems during early stages of planetary system formation. According to planet-formation theories, such as the core
Generation of Unbound Comets and Planets by Planetary Systems
We present a three-dimensional model of the evolution of the asteroid–cometary–planetary (ACP) component of the Solar System under the gravitational influence of Jupiter. We demonstrate the origin of
Giant planet effects on terrestrial planet formation and system architecture
The giant planets of the solar system likely played a large role in shaping the architecture of the terrestrial planets. Using an updated collision model, we conduct a suite of high resolution N-body
N-body simulations of planet formation via pebble accretion I: First Results
Context. Planet formation with pebbles has been proposed to solve a couple of long-standing issues in the classical formation model. Some sophisticated simulations have been done to confirm the


The Effect of Planets Beyond the Ice Line on the Accretion of Volatiles by Habitable-Zone Rocky Planets
Models of planet formation have shown that giant planets have a large impact on the number, masses, and orbits of terrestrial planets that form. In addition, they play an important role in delivering
Formation of terrestrial planets in a dissipating gas disk
Debris disks as signposts of terrestrial planet formation
There exists strong circumstantial evidence from their eccentric orbits that most of the known extra-solar planetary systems are the survivors of violent dynamical instabilities. Here we explore the
Planet Scattering Around Binaries: Ejections, Not Collisions
Transiting circumbinary planets discovered by Kepler provide unique insight into binary star and planet formation. Several features of this new found population, for example the apparent pile-up of

Debris disks as signposts of terrestrial planet formation - II. Dependence of exoplanet architectures on giant planet and disk properties
We present models for the formation of terrestrial planets, and the collisional evolution of debris disks, in planetary systems that contain multiple marginally unstable gas giants. We previousl y
Circumbinary planets whose orbits become unstable may be ejected, accreted, or even captured by one of the stars. We quantify the relative rates of these channels, for a binary of secondary star's
A Decreased Probability of Habitable Planet Formation around Low-Mass Stars
Smaller terrestrial planets (P0.3 M⊕) are less likely to retain the substantial atmospheres and ongoing tectonic activity probably required to support life. A key element in determining whether
