Free-Floating Planets and Stellar Clusters

American Scientist, 2002
The existence of planets outside our solar system has been a licate matter in astronomy ever since the 16th-century philosopher Giordano Bruno was burned at the stake for (among other things) proposing that the universe holds an infinite number of other worlds.

Free-floating Planets in Orion

Science, 2000
ASTRONOMY Extrasolar planets and brown dwarfs have been discovered with increasing frequency around young stars, yet still more discoveries will be needed to understand conditions under which a star or a planet will form from the collapse of a molecular cloud or other processes.

Simulation of Images of Protoplanetary Disks after Collision with Free-Floating Planets

Astronomy letters
Observational manifestations of disturbances in a protoplanetary disk caused by a collision with a massive planet are studied. It is assumed that the planet moves along a parabolic trajectory that intersects the disk plane near the star.

On the capture of free floating planets

2015
Diese Masterarbeit bearbeitet die Interaktion zwischen einem free-floating planet und einem gebundenen Stern-Planeten System. Besonders wird dabei auf den Fall einge- gangen, in dem der free-floating planet vom System eingefangen wird und auf einer Bahn gravitativ gebunden bleibt. Sogenannte free-floating planets werden laufend entdeckt.

Constraints on the free-floating planets supporting aqueous life

Acta Astronautica, 2011
Abstract Optically thick atmospheres provide conditions for life on free-floating planets (FFPs). These atmospheres may ensure conservation of energy released by radio-nuclides and the long-term thermal stability of a necessary life-supporting liquid solvent (e.g. water) on the surface.
