Free-floating planets from core accretion theory: microlensing predictions [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2016 We calculate the microlensing event rate and typical time-scales for the free-floating planet (FFP) population that is predicted by the core accretion theory of planet formation.

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 ...

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 origin of free-floating planets [PDF]
Astrophysics and Space Science, 2023 Free-floating planets (FFPs) are the lightest products of star formation and they carry important information on the initial conditions of the environment in which they were formed. They were first discovered in the 2000 s but still few of them have been

Euclid-Roman joint microlensing survey: early mass measurement, free floating planets and exomoons [PDF]
Astronomy & Astrophysics, 2022 As the Kepler mission has done for hot exoplanets, the ESA Euclid and NASA Roman missions have the potential to create a breakthrough in our understanding of the demographics of cool exoplanets, including unbound, or"free-floating", planets (FFPs).

The JWST/NIRISS Deep Spectroscopic Survey for Young Brown Dwarfs and Free-floating Planets [PDF]
The Astronomical JournalThe discovery and characterization of free-floating planetary-mass objects (FFPMOs) is fundamental to our understanding of star and planet formation. Here we report results from an extremely deep spectroscopic survey of the young star cluster NGC1333 ...

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.

Free-Floating Planets, the Einstein Desert, and 'Oumuamua [PDF]
, 2022 : We complete the survey for finite-source/point-lens (FSPL) giant-source events in 2016-2019 KMTNet microlensing data. The 30 FSPL events show a clear gap in Einstein radius, 9 µ as < θ E < 26 µ as, which is consistent with the gap in Einstein timescales

Disc fragmentation. I. Ejection of Jupiter-mass Free Floating Planets from growing binary systems [PDF]
Monthly notices of the Royal Astronomical SocietyOver the past 25 years, observations have uncovered a large population of free-floating planets (FFPs), whose origins remain debated. Massive FFPs (several Jupiter masses or more) may form via gravitational collapse of molecular clouds, similar to ...

Secure Identification of Free-Floating Planets
The Astrophysical Journal, 2006 Among the methods proposed to detect extrasolar planets, microlensing is the only technique that can detect free-floating planets. Free-floating planets are detected through the channel of short-duration isolated lensing events.
