The Astrophysical JournalThe discovery of numerous free-floating planets (FFPs) has intensified interest in their origins and dynamical histories. A leading formation mechanism is planet–planet scatterings in unstable multiplanetary systems, which can naturally lead to planetary

On the properties of free-floating planets originating in circumbinary planetary systems
Monthly Notices of the Royal Astronomical SocietyABSTRACT Free-floating planets are a new class of planets recently discovered. These planets don’t orbit within stellar systems, instead living a nomadic life within the galaxy. How such objects formed remains elusive. Numerous works have explored mechanisms to form such objects, but have not yet provided predictions on their ...

Masses for free-floating planets and dwarf planets [PDF]
Research in Astronomy and Astrophysics, 2021 Abstract The mass and distance functions of free-floating planets (FFPs) would give major insights into the formation and evolution of planetary systems, including any systematic differences between those in the disk and bulge.

Free-floating planets in stellar clusters? [PDF]
Monthly Notices of the Royal Astronomical Society, 2001 We have simulated encounters between planetary systems and single stars in various clustered environments. This allows us to estimate the fraction of systems liberated, the velocity distribution of the liberated planets, and the separation and eccentricity distributions of the surviving bound systems.

Hunting for Cold Exoplanets via Microlensing
Comptes Rendus. Physique, 2023 Microlensing can detect planets at distances ranging from a few hundred parsecs all the way to the Galactic center. The maximum sensitivity is reached for systems that are located half way to the galactic center, with planets orbiting the lens star at a ...

Interaction of free-floating planets with a star–planet pair [PDF]
Celestial Mechanics and Dynamical Astronomy, 2012 The recent discovery of free-floating planets and their theoretical interpretation as celestial bodies, either condensed independently or ejected from parent stars in tight clusters, introduced an intriguing possibility. Namely, that some exoplanets are not condensed from the protoplanetary disk of their parent star.

Are There Terrestrial Planets Lurking in the Outer Solar System?
The Astrophysical Journal Letters, 2023 Motivated by recent measurements of the free-floating-planet mass function at terrestrial masses, we consider the possibility that the solar system may have captured a terrestrial planet early in its history.

The Astronomical Journal, 2023 Recent detections of extremely short-timescale microlensing events imply the existence of a large population of Earth- to Neptune-mass planets that appear to have no host stars.

Primordial Planets with an Admixture of Dark Matter Particles and Baryonic Matter
Universe, 2023 It has been suggested that primordial planets could have formed in the early universe and the missing baryons in the universe could be explained by primordial free-floating planets of solid hydrogen.
