Monitoring PSR B1509-58 with RXTE: Spectral analysis 1996-2010

摘要

We present an analysis of the X-ray spectra of the young, Crab-like pulsar PSR B1509-58 (pulse period P ~ 151 ms) observed by RXTE over 14 years since the beginning of the mission in 1996. The uniform dataset is especially well suited for studying the stability of the spectral parameters over time as well as for determining pulse phase resolved spectral parameters with high significance. The phase averaged spectra as well as the resolved spectra can be well described by an absorbed power law.
