On the origin of planets at very wide orbits from the re-capture of free floating planets [PDF]
, 2012 In recent years several planets have been discovered at wide orbits (>100 AU) around their host stars. Theoretical studies encounter difficulties in explaining their formation and origin.

On the properties of free-floating planets originating in circumbinary planetary systems [PDF]
Monthly notices of the Royal Astronomical SocietyFree-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

Detectability of Free Floating Planets in Open Clusters with JWST [PDF]
, 2013 Recent observations have shown the presence of extra-solar planets in Galactic open stellar clusters, as in the Praesepe (M44). These systems provide a favorable environment for planetary formation due to the high heavy-element content exhibited by the ...

The microlensing rate and distribution of free-floating planets towards the Galactic bulge [PDF]
, 2016 Ground-based optical microlensing surveys have provided tantalising, if inconclusive, evidence for a significant population of free-floating planets (FFPs).

Disc fragmentation. II. Ejection of low mass Free Floating Planets from growing binary systems
Monthly notices of the Royal Astronomical SocietyObservations indicate that disc fragmentation due to Gravitational Instability (GI) is the likely origin of massive companions to stars, such as giant planets orbiting M-dwarf stars, Brown Dwarf (BD) companions to FGK stars, and binary stars with ...

ON THE FEASIBILITY OF CHARACTERIZING FREE-FLOATING PLANETS WITH CURRENT AND FUTURE SPACE-BASED MICROLENSING SURVEYS [PDF]
, 2016 Simultaneous space- and ground-based microlensing surveys, such as K2's Campaign 9 (K2C9) and WFIRST, facilitate measuring the masses and distances of free-floating planet (FFP) candidates, which are identified as single-lens events with timescales that ...

The Demographics of Rocky Free-floating Planets and their Detectability by WFIRST [PDF]
The Astrophysical Journal, 2017 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 ...

The coolest 'stars' are free-floating planets [PDF]
, 2014 We show that the coolest known object that is probably formed in a star-like mode is a free-floating planet. We discovered recently that the free-floating planetary mass object OTS,44 (M9.5, ~12 Jupiter masses, age ~2 Myr) has significant accretion and a substantial disk.

A rich population of free-floating planets in the Upper Scorpius young stellar association [PDF]
Nature Astronomy, 2021 The nature and origin of free-floating planets (FFPs) are still largely unconstrained because of a lack of large homogeneous samples to enable a statistical analysis of their properties.

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.
