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)
with 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.
