On the properties of free-floating planets originating in circumbinary planetary systems [PDF]
Monthly Notices of the Royal Astronomical SocietyABSTRACT Free-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 form such objects, but have not yet provided predictions on their ...

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.

The Demographics of Rocky Free-floating Planets and their Detectability by WFIRST [PDF]
The Astrophysical Journal, 2017 Abstract 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 of the the interplanetary medium; falls into the star; or is ejected from ...

Tilted Circumbinary Planetary Systems as Efficient Progenitors of Free-floating Planets [PDF]
The Astrophysical Journal LettersThe dominant mechanism for generating free-floating planets has so far remained elusive. One suggested mechanism is that planets are ejected from planetary systems due to planet–planet interactions.

Exploring Free Floating Planets with Microlensing [PDF]
, 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.

The Astrophysical JournalThe discovery of numerous free-floating planets (FFPs) has intensified interest in their origins and dynamical histories. A leading formation mechanism is planet–planet scatterings in unstable multiplanetary systems, which can naturally lead to planetary

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

Masses for free-floating planets and dwarf planets [PDF]
Research in Astronomy and Astrophysics, 2021 Abstract The mass and distance functions of free-floating planets (FFPs) would give major insights into the formation and evolution of planetary systems, including any systematic differences between those in the disk and bulge.

Globulettes: Formation Sites Of Free Floating Planets?
, 2017 NIR imaging and ALMA arc-second resolution CO, CS and H2CO imaging of two typical Rosette Nebula globulettes is discussed. Velocity structure is observed in the 12CO line whereas the observed CS line widths are are extremely narrow, 0.3kms-1-0.4kms-1, indicating practically no internal motions in the very core.
