2008. Mar. 25 : We held a meeting for summarizing activities of our COE program (Oct.2003- Mar.2008) on Mar.17, and Mar.18 at Kobe University. [link] 2008. Mar. 11 : Several posters were added to the Poster Gallery. [link] 2008. Feb. 28 : Press Conference on Planet X was held on February 27 at National Astronomical Observatory, and on February 28 at Kobe University. [link] 2007. Dec. 21 : Dr. Patryk Lykawka and Prof. Tadashi Mukai carried out extensive simulations for dynamical evolution of planetesimal disks. The simulation reproduces all main aspects of trans-Neptunian belt architecture and offers the presence of outer planet with mass of 0.3-0.7 Earth mass, later acquired an inclined stable orbit (>100 AU;20-40 deg).
