Suzaku observation of Be/X-ray binary pulsar EXO 2030+375
Naik, Sachindra; Jaisawal, Gaurava K.
We study the timing and spectral properties of Be/X-ray binary pulsar EXO 2030+375 using a Suzaku observation taken on 2012 May 23, during a less intense Type I outburst. Pulsations were clearly detected in the X-ray light curves at a barycentric period of 41.2852 s, which suggest that the pulsar is spinning-up. The pulse profiles were found to be…
Understanding the X-ray spectrum of anomalous X-ray pulsars and soft gamma-ray repeaters
Liu, Yuan; Guo, Yan-Jun; Tong, Hao +3 more
Hard X-rays above 10 keV are detected from several anomalous X-ray pulsars (AXPs) and soft gamma-ray repeaters (SGRs), and different models have been proposed to explain the physical origin within the frame of either a magnetar model or a fallback disk system. Using data from Suzaku and INTEGRAL, we study the soft and hard X-ray spectra of four AX…
