Masses for free-floating planets and dwarf planets [PDF]
Research in Astronomy and Astrophysics, 2021 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.

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.

Free-floating planets in the Milky Way [PDF]
Arabian Journal of Mathematics, 2019 Gravitational microlensing is a powerful method to search for and characterize exoplanets, and it was first proposed by Paczyński in 1986. We provide a brief historical excursus of microlensing, especially focused on the discoveries of free-floating ...

Dynamical Instability of Multiplanet Systems and Free-floating Planets
The Astrophysical JournalThe ejection of planets by the instability of planetary systems is a potential source of free-floating planets. We numerically simulate multiplanet systems to study the evolution process, the properties of the surviving systems, and the statistics of the

Planet-Planet Scattering Alone Cannot Explain the Free-Floating Planet Population [PDF]
Monthly Notices of the Royal Astronomical Society: Letters, 2012 Recent gravitational microlensing observations predict a vast population of free-floating giant planets that outnumbers main sequence stars almost twofold.

Microlensing by Kuiper, Oort, and Free-Floating Planets [PDF]
Journal of The Korean Astronomical Society, 2016 Microlensing is generally thought to probe planetary systems only out to a few Einstein radii. Microlensing events generated by bound planets beyond about 10 Einstein radii generally do not yield any trace of their hosts, and so would be classified as ...

Capture of free-floating planets by planetary systems [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 Evidence of exoplanets with orbits that are misaligned with the spin of the host star may suggest that not all bound planets were born in the protoplanetary disk of their current planetary system.

Microlensing planets in M22: free-floating or bound? [PDF]
Astronomy & Astrophysics, 2001 We use detailed numerical simulations and theoretical estimates to show that, if confirmed, the unusually brief microlensing events observed by Sahu et al.

On the properties of free-floating planets originating in circumbinary planetary systems [PDF]
Monthly Notices of the Royal Astronomical SocietyFree-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

On the origin of planets at very wide orbits from the re-capture of free floating planets [PDF]
The Astrophysical Journal, 2012 In recent years several planets have been discovered at wide orbits (>100 AU) around their host stars. Theoretical studies encounter difficulties in explaining their formation and origin.
