The astrometric signal of microlensing events caused by free floating planets [PDF]
Astrophysics and Space Science, 2018 Astrometric observations of microlensing events can be used to obtain important information about lenses. During these events, the shift of the position of the multiple image centroid with respect to the source star location can be measured. This effect,

Predicting the Galactic population of free-floating planets from realistic initial conditions [PDF]
Monthly notices of the Royal Astronomical SocietyWe present the first prediction for the mass distribution function of Galactic free-floating planets (FFPs) that aims to accurately include the relative contributions of multiple formation pathways and stellar populations.

On the detection of binary free-floating planets in the Roman Galactic Exoplanet Survey [PDF]
Monthly notices of the Royal Astronomical SocietyThe recent discovery of 40 binary Jupiter-mass free-floating planets in the Trapezium cluster by the James Webb Space Telescope(Pearson & McCaughrean 2023) has opened new windows and questions in planets studies.

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).

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 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.

Presence of liquid water during the evolution of exomoons orbiting ejected free-floating planets [PDF]
International Journal of Astrobiology, 2023 Free-floating planets (FFPs) can result from dynamical scattering processes happening in the first few million years of a planetary system's life. Several models predict the possibility, for these isolated planetary-mass objects, to retain exomoons ...
