Traditionally, scientists believed rogue planets were formed within and then ousted from an existing solar system.

      Thankfully almost all astronomy/astrophysics research papers are also provided through open access for free. Unfortunately they can be difficult to find for the non-professional astronomer. Here is the link for the open access version of this paper: http://arxiv.org/pdf/1305.2485v2.pdf
