Study: 'Hot Jupiter' exoplanets formed extremely rapidly
Paris (UPI) Sep 16, 2015
For years, astronomers have been stumped by a rare type of exoplanet known as "hot Jupiters." Hot Jupiters are gas giants which orbit unusually close to their stars. Scientists have theorized that hot Jupiters form in the outer reaches of their solar systems and drift inward toward their host star - the opposite of the trajectory of the real Jupiter and most other gas giants. It's their arrival near their stars that makes them hot and causes their gas to expand to such a large size. Unt ... read more
