Link found between age of stars and frequency of hot Jupiters

A team of astronomers and astrophysicists affiliated with several institutions in China, working with one colleague from Centro Ricerche Enrico Fermi, in Italy, and another from the University of Utah, in the U.S., has found a link between star age and the frequency of hot Jupiters. In their study, reported in Proceedings of the National Academy of Sciences, the group characterized the ages of a large number of star systems that have Jupiter-like exoplanets and compared them.
