HD 133131

(binary star system with exoplanets)

HD 133131 is binary star consisting of two Sun-like G-type stars (though older and with lower metallicity), both of which have extra-solar planets, one star with a gas giant, and the other with two. Gas giants have generally been found around higher metallicity stars and theories have been developed to explain this, so this system is atypical.
