The brown dwarf GJ 504 B's system

An article published in “The Astronomical Journal” offers an explanation of the formation mechanisms of gas giant planets and brown dwarfs bringing evidence that these are two different mechanisms. A team of astronomers led by Brendan Bowler of the University of Texas, Austin, conducted observations at the Keck Observatory and with the Subaru Telescope, both in Hawaii, accompanied by computer simulations using the free / open source orbitize! software to try to understand if there were orbital differences that indicated a different origin between these objects. Their conclusion is that brown dwarfs have significantly more elliptical orbits.
