British scientists from Queen Mary University of London conducted a study that reveals the origin of wandering planets. The results of this study were published on the scientific publications portal arXiv.
Rogue planets, or so-called rogue planets, are cosmic objects of planetary mass that move independently of any stars. They remain poorly understood, largely due to difficulties in detecting them.
There are several known ways in which wandering planets can form: they can form in protoplanetary disks around young stars or arise in gas and dust clouds.
The new study involved a series of computer simulations aimed at understanding the processes that cause planets to leave their orbits and travel through space.
According to the simulations, the main source of wandering planets are binary or circumbinary star systems, where planets orbit a pair of stars. The study showed that such systems could eject two to seven planets with a mass comparable to Earth into space during their lifetime.
However, the ejection rate of planets weighing 100 times Earth or more drops to 0.6.
When modeling, scientists took into account several factors, including the initial mass of the disk, the influence of the external environment and the level of turbulence in the disk. Each simulation covered a period of 10 million years, long enough for the system to form.
In the future, astronomers plan to determine the types of stars that most often eject planets into outer space.
