Examining the population of free floating planets

- Abstract
- Scattered in our galaxy today are planets that have no host star and are only bound to the galaxy. These so called free floating planets are believed to be formed around stars but have later been ejected by passing stars perturbing their orbits, or have undergone close interactions with another planet in a planetary system. This results in one of the planets becoming tightly bound in an often eccentric orbit and the other one ejected. In this project, we simulate the process of stars and their attributes that favours the creation of planets, which through planet-planet interaction processes, populate as free floating planets. The results show that the population of free floaters are much less than expected when compared to the latest... (More)

The results show that the population of free floaters are much less than expected when compared to the latest observational data. An explanation might be the problem that observations don't distinguish between free floating planets and planets in very wide orbits, or that we simply don't know enough about the parameters involved.
