Astronomers Uncover Double Hot Jupiters in Binary Star Systems
A team of astronomers has discovered a rare phenomenon of 'double hot Jupiters' in binary star systems. These scorching hot gas giants challenge traditional planet formation theories. The researchers propose a mechanism called ZLK migration to explain the origin of these unique exoplanets.
Astronomers may have uncovered the origins of the universe's double hot Jupiters, rare gas giants orbiting close to their parent stars. These exoplanet pairs are found in binary star systems, challenging planet formation theories. The team suggests that the ZLK mechanism can lead to the formation of hot Jupiters around each star.
The ZLK migration process involves planets being influenced by the gravity of another object, causing them to migrate close to their parent star. Through simulations, the team showed how planets in binary systems can undergo mirrored migration, resulting in both stars having hot Jupiters.
The research, published in The Astrophysical Journal, makes planet-formation models more interesting and highlights the mystery of hot Jupiters. To find more double hot Jupiters, astronomers can revisit binary systems with the right star separation.
