Satoshi CHIBA and Toshiki MARUYAMA Advanced Science Research Center (Tokai Site) Japan Atomic Energy Research Institute Tokai-mura, Naka-gun, Ibaraki-ken (Received July 5, 1999) The first symposium on Science of Hadrons under Extreme Conditions, organized by the Research Group for Hadron Science, Advanced Science Research Center, was held at Tokai Research Establishment of JAERI on March 11 and 12, 1999. The symposium was devoted for discussions and presentations of research results in wide variety of fields such as observation of X-ray pulsars, theoretical studies of nuclear matter, nuclear struc- ture, low- and high-energy nuclear reactions and QCD. Thirty seven papers on these topics presented at the symposium aroused lively discussions among approximately 50 participants. Keywords: Proceedings, Hadrons under Extreme Conditions, Neutron Stars, X-ray Pulsars, Nuclear Matter, Nuclear Structure, Nuclear Reactions, QCD Organizers:S. Chiba, T. Maruyama, T. Kido, Y.

X-ray Pulsar Rush in 1998 3-E fttih it* E?i, Brt « 1 Abstract We present recent remarkable topics about discoveries of X-ray pulsars. 1. Pulsations from two Soft Gamma-ray Repeaters These pulsars have enormously strong magnetic field (B~1015 G), thus these are called as "magnetar", new type of X-ray pulsars. 2. New Crab-like pulsars These discoveries lead to suggesting universality of Crab-like pulsars. 3. An X-ray bursting millisecond pulsar This is strong evidence for the recycle theory of generating radio millisecond pulsars. 4. X-ray pulsar rush in the SMC This indicates the younger star formation history in the SMC.
