Exploring Free Floating Planets With Microlensing
, 2012 About one year ago, the MOA microlensing team announced the discovery of a free floating planet population with the method of gravitational microlensing (Sumi et al. 2011). In this thesis, we test the possibility of these planets being in reality bound but getting confused as free floating because of the shape of their light curve.

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.

Searching for Free-floating Planets with TESS: Results from Sectors 61–65 [PDF]
The Astronomical JournalThough free-floating planets (FFPs) may outpopulate their bound counterparts in the terrestrial-mass range, they remain one of the least explored exoplanet demographics.

Properties of Free-floating Planets Ejected through Planet–Planet Scattering
The Astrophysical JournalMultiple studies show that planet–planet scattering plays a key role in the dynamical evolution of planetary systems. It can also contribute to the census of free-floating planets.

How Rare Are TESS Free-floating Planets?
The Astrophysical Journal LettersRecently, Kunimoto et al. claimed that a short-lived signal in the Transiting Exoplanet Survey Satellite (TESS) Sector 61 database was possibly caused by a microlensing event with a terrestrial-mass free-floating planet (FFP) lens.

Free-floating "planets'' in the macrolensed quasar Q2237+0305 [PDF]
Monthly Notices of the Royal Astronomical SocietyABSTRACT It has been claimed that the variability of field quasars resembles gravitational lensing by a large cosmological population of free-floating planets with mass $\sim\!\! 10\ {\rm M}_{\oplus }$. However, Galactic photometric monitoring experiments, on the other hand, exclude a large population of such planetary-mass gravitational

Free-floating Planet Mass Function from MOA-II 9 yr Survey toward the Galactic Bulge [PDF]
The Astronomical Journal, 2023 We present the first measurement of the mass function of free-floating planets (FFPs), or very wide orbit planets down to an Earth mass, from the MOA-II microlensing survey in 2006–2014.

Close encounters involving free-floating planets in star clusters [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 Instabilities in planetary systems can result in the ejection of planets from their host system, resulting in free-floating planets (FFPs). If this occurs in a star cluster, the FFP may remain bound to the star cluster for some time and interact with the
