The newly detected worlds are enormous and have very long orbital periods ranging from nearly two to slightly more than 4 Earth years. The researchers used the 1.5 m telescope at the Cerro Tololo Inter-American Observatory and the 2.2 m telescope at La Silla observatory in Chile, and the 3.9 m Anglo-Australian telescope in Australia. 4 giant stars were studied— HIP8541, HIP74890, HIP84056 and HIP95124 for having planetary companions.
