Scientists from Yale University conducted research in search of planets that may be suitable for life.
In multistellar systems, where multiple stars orbit a common center of mass, exoplanets are subject to strong gravitational perturbations. This can cause planetary orbits to become unstable and planets to fly out of the system or collide with other bodies.
Scientists from Yale University decided to find out how often exoplanets with stable orbits that can support life can exist in such systems. To do this, they used computer modeling and analysis of data from the Kepler space telescope, writes Earth sky.
They found that in some cases, exoplanets can remain stable even with three or four stars in the system. However, for this, the planets need to be at a sufficient distance from the stars and have a small orbital eccentricity. Such planets could receive enough light and heat from their stars to support liquid water on the surface, making life possible there. So far, researchers have not established whether such planets are inhabited by some forms of life, but there is a possibility of this.
“We show for the first time that there is an unexpected accumulation of systems where everything is consistent. The planets rotate in exactly the same direction in which the first star rotates, and the second star rotates around this system in the same plane as the planets“, the scientists commented.
Scientists hope that their research will help in the search and study of potentially habitable exoplanets in multistellar systems.
Previously, scientists managed to unravel secret “alien mummies” from Peru. As it turned out, the remains have nothing to do with extraterrestrial civilizations.
And on the ring of Tutankhamun, which was discovered in 1922 in his tomb, scientists found an unusual image. Some consider it proof of the pharaoh’s connection with aliens.
