Abstract
We report the first discovery of a multi-planetary system by the HATSouth network, HATS-59b,c, a planetary system with an inner transiting hot Jupiter and an outer cold massive giant planet, which was detected via radial velocity. The inner transiting planet, HATS-59b, is on an eccentric orbit with e = 0.129 +/- 0.049, orbiting a V = 13.951 +/- 0.030 mag solar-like star (M-star = 1.038 +/- 0.039 M-circle dot and R-star = 1.036 +/- 0.067 R-circle dot) with a period of 5.416081 +/- 0.000016 days. The outer companion, HATS-59c is on a circular orbit with m sin i = 12.70 +/- 0.87 M-J and a period of 1422 +/- 14 days. The inner planet has a mass of 0.806 +/- 0.069 M-J and a radius of 1.126 +/- 0.077 R-J, yielding a density of 0.70 +/- 0.16 g cm(-3). Unlike most planetary systems that include only a single hot Jupiter, HATS-59b, c includes, in addition to the transiting hot Jupiter, a massive outer companion. The architecture of this system is valuable for understanding planet migration.
