Planetary system
HD 45364 is one of only a relative few systems that have had more than one exoplanet discovered in its orbit. The two planets, HD 45364 b and HD 45364 c respectively, were both discovered in August 2008.
Formation scenario
A detailed analysis of the formation scenario revealed that the previously reported orbital configuration might not be correct. The eccentricities are a factor of 4-5 too large to be consistent with standard planet formation theories.[1] This is the first time that planet formation theory was able to predict new orbital parameters of a planetary system.
