Hot Jupiters are giant gas exoplanets that orbit around their host stars. Even though their names might suggest otherwise, they’re a lot bigger and hotter than Jupiter.
According to a report from the University of Arecibo, 740 of the 3,442 exoplanets that exist are Hot Jupiters. These giant exoplanets are pretty interesting, and some of them are so big, they defy the theories of planetary formation. But, there’s new research tht shows that Hot Jupiters actually aren’t that big, they just expand over time.
The Hungarian Automated Telescope Network in Arizona and Hawaii has allowed scientists to identify two Hot Jupiters. HAT-P-65b and HAT-P-66b are their names, and they are 2,745 and 3,025 lighyears from Earth, respectively. Each of the exoplanets orbit their stars 10 times closer than Mercury’s distance from our sun.
All of this information has been available as a possible explanation for the size Hot Jupiters can reach for a while. But until now, no one has been able to demonstrate how the exoplanets are able to move their energy to their interiors and expand.
This study has not only shed a lot of light on Hot Jupiters. It’s also helping us understand how radiation can impact a planet’s evolution. All of the information gathered by Hartman and his team will mean more thorough studies of other exoplanets.
