���� English HOME ABOUT KIAA PEOPLE ACTIVITIES NEWS SCIENCE OPPORTUNITIES OUTREACH VISITOR INFO ADMIN Search @ KIAA-PKU Featured Science Search New Patterns in Planet Distributions Subo Dong ( �� 勃 ) joined the faculty of KIAA in Fall 2013 through the 1000 Talents Program for young researchers ( 青年千人 � 划 ). One of his research interests is to Upcoming Events robustly derive the distributions of extrasolar planets in order to find clues on how planet systems form and evolve. In a paper recently published in the Astrophysical How much cosmological Journal (http://arxiv.org/abs/1212.4853), he and Zhaohuan Zhu (Princeton information can be University) determined the distributions of planets down to Earth size and in orbits measured? closer than Venus. Speaker: Yinzhe Ma, University of British Columbia Wind Braking of AXP/SGRs Time: Mon, 2014-01-06 12:00 to 13:00 Anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs) are believed Location: DoA, Rm 2907 to be magnetars: peculiar neutron stars powered by their super strong magnetic field. Unfortunately, none of the predictions of traditional magnetar models Finding Transiting successfully explain their properties. In a recent paper, the group of Prof. Renxin Xu Exoplanets and (PKU Department of Astronomy, with joint appointment at the KIAA), in Characterizing their collaboration with Dr. Hao Tong of the Xinjiang Astronomical Observatory, show Atmospheres: HATSouth that a wind braking mechanism in magnetars, where the energy release generates a and ACCESS strong wind, provides a natural understanding of the multiwavelength observational Speaker: Andrés Jordán (PUC) behavior of AXPs and SGRs.
