Scientists from the University of Witwatersrand (South Africa) and the University of Grenoble (France) have identified areas where exoplanets can exist in systems with three stars. The analysis has shown that there are large-scale stable regions in which alien worlds can be located, both in binary and triple star systems. Double star system - two stars revolve around each other, and a triple combines three objects, where the third revolves around two main ones.
In such systems, there is a complex dynamics, so they could not imagine that the exoplanets located there had a stable orbital path. To understand this question, the researchers conducted more than 45,000 computer simulations for 3 years, examining all possible combinations of orbits, sizes, masses, and other variables. It turns out that exoplanets can exist in such systems. In addition, it was possible to identify the probable areas of their detection. The models were launched for a period of 1-10 million years to check the stability of the system. If the planet was ejected during this time period, then the system was recognized as unstable. Exoplanets - worlds located outside the solar system. Of the 3,700 worlds found, less than 40 live in triple star systems. But perhaps the whole point is that such systems are still poorly investigated. Further observations may lead to future large-scale campaigns to study the planets in systems with three stars.
