The research, led by Professor Elcio Abdalla from the Institute of Physics at the Universidade de Sao Paulo, Brazil, appears in a recent issue of the astronomical journal Physics Letters B.

In a paper published in The Astronomical Journal, Dr. Brown and Dr. Batygin lay out a detailed circumstantial argument for the planet's existence in what astronomers have observed-a half-dozen small bodies in distant elliptical orbits.

布朗和巴蒂金在《天文学杂志》（The Astronomical Journal）上联合发表了一篇论文，提出详细的旁证，认为天文学家们观测到的现象——在遥远的椭圆轨道上运行的六个小天体——证明了这颗行星的存在。
