The Stochastic X-ray Variability of the Accreting Millisecond Pulsar
In this work I report on the stochastic X-ray variability of the 340 Hz accreting millisecond pulsar MAXI J0911–655. Analyzing pointed observations of the XMM-Newton and NuSTAR observatories I find that the source shows broad band-limited stochastic variability in the 0.01− 10 Hz range, with a total fractional variability of ∼ 24% rms in the 0.4− 3 keV energy band, which increases to ∼ 40% rms ...
متن کاملHard X - Ray Spectroscopy and Pulsar Phase Analysis ofthe
We report OSSE observations of the bursting X-ray pulsar GRO J1744{28 made in December 1995 and January 1996 at hard X-ray energies > 35 keV. The pulse proole of the persistent (i.e. non-bursting) pulsar emission is t with a sinusoid in the energy range 35{90 keV. Residuals reveal a second harmonic amplitude of 3:0 0:5% of the fundamental. The distribution of time intervals between bursts measu...

متن کاملX - ray spectrum of the accreting binary X - ray pulsar GX
We present here high resolution X-ray spectrum of the accreting binary X-ray pulsar GX 1+4 obtained with the High Energy Transmission Grating (HETG) instrument of the Chandra X-ray Observatory. This was supplemented by a simultaneous observation with the Proportional Counter Array (PCA) of the Rossi X-ray Timing Explorer (RXTE). During this observation, the source was in a somewhat low intensit...
