Abstract
The isolated neutron star candidate RBS 1223 was observed with the Advanced CCD Imaging Spectrometer aboard the Chandra observatory on 2000 June 24. A timing analysis of the data yielded a periodic modulation with a period s. Using ROSAT HRI archived observations we detected a period s and determined period derivative s . The detection of this period and indicates that RBS 1223 has a “characteristic” age of 6000-12 000 years and huge magnetic field at the surface () typical for anomalous pulsars (AXPs).Keywords
