Free‐floating Planets in Stellar Clusters: Not So Surprising [PDF]
The Astrophysical Journal, 2002 We find that free-floating planets can remain bound to an open cluster for much longer than was previously calculated: of the order of the cluster half-mass relaxation timescale as opposed to the crossing time. This result is based on N-body simulations performed with the new GRAPE-6 special purpose hardware and is important in the context of the ...

Geosciences, 2018 “Free-floating, non-deuterium-burning, substellar objects” are isolated bodies of a few Jupiter masses found in very young open clusters and associations, nearby young moving groups, and in the immediate vicinity of the Sun.

Microlensing due to free-floating moon-planet systems
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Gravitational microlensing is a powerful method for detecting and characterizing free-floating planetary-mass objects (FFPs). FFPs could have exomoons rotating them. In this work, we study the probability of realizing these systems (i.e. free-floating moon-planet ones) through microlensing observations. These systems make mostly

KMT-2022-BLG-2397: Brown Dwarf at the Upper Shore of the Einstein Desert
The Astronomical Journal, 2023 We measure the Einstein radius of the single-lens microlensing event KMT-2022-BLG-2397 to be θ _E = 24.8 ± 3.6 μ as, placing it at the upper shore of the Einstein Desert, 9 ≲ θ _E / μ as ≲ 25, between free-floating planets (FFPs) and bulge brown dwarfs ...

Linking the formation and fate of exo-Kuiper belts within solar system analogues [PDF]
, 2020 Escalating observations of exo-minor planets and their destroyed remnants both passing through the solar system and within white dwarf planetary systems motivate an understanding of the orbital history and fate of exo-Kuiper belts and planetesimal discs.

Microlensing Characterization of Wide-Separation Planets
, 2004 With their excellent photometric precision and dramatic increase in monitoring frequency, future microlensing survey experiments are expected to be sensitive to very short time-scale, isolated events caused by free-floating and wide-separation planets ...

No large population of unbound or wide-orbit Jupiter-mass planets
, 2017 Gravitational microlensing is the only method capable of exploring the entire population of free-floating planets down to Mars-mass objects, because the microlensing signal does not depend on the brightness of the lensing object.

Characterization of Microlensing Planets with Moderately Wide Separations
, 2009 In future high-cadence microlensing surveys, planets can be detected through a new channel of an independent event produced by the planet itself. The two populations of planets to be detected through this channel are wide-separation planets and free ...

Measurement of the Free-Floating Planet Mass Function with Simultaneous Euclid and WFIRST Microlensing Parallax Observations [PDF]
, 2019 Free-floating planets are the remnants of violent dynamical rearrangements of planetary systems. It is possible that even our own solar system ejected a large planet early in its evolution.

Optimal Survey Strategies and Predicted Planet Yields for the Korean Microlensing Telescope Network [PDF]
, 2014 The Korean Microlensing Telescope Network (KMTNet) will consist of three 1.6m telescopes each with a 4 deg^{2} field of view (FoV) and will be dedicated to monitoring the Galactic Bulge to detect exoplanets via gravitational microlensing.
