Discovery of a 205.89 Hz Accreting–millisecond X-ray Pulsar in the Globular Cluster
We report the discovery of the second accreting millisecond X-ray pulsar (AMXP) in the globular cluster NGC 6440. Pulsations with a frequency of 205.89 Hz were detected with the Rossi X-Ray Timing Explorer on August 30th, October 1st and October 28th, 2009, during the decays of . 4 day outbursts of a newly X-ray transient source in NGC 6440. By studying the Doppler shift of the pulsation freque...
متن کاملAn Xmm-newton Study of the 401 Hz Accreting Pulsar Sax J1808.4–3658 in Quiescence
SAX J1808.4–3658 is a unique source being the first Low Mass X–ray Binary showing coherent pulsations at a spin period comparable to that of millisecond radio pulsars. Here we present an XMM-Newton observation of SAX J1808.4–3658 in quiescence, the first which assessed its quiescent luminosity and spectrum with good signal to noise. XMM-Newton did not reveal other sources in the vicinity of SAX...
متن کاملTiming and Spectral Properties of the Accreting Millisecond Pulsar Swift J1756.9–2508
SWIFT J1756.9-2508 is one of the few accreting millisecond pulsars (AMPs) discovered to date. We report here the results of our analysis of its aperiodic X-ray variability, as measured with the Rossi X-ray Timing Explorer during the 2007 outburst of the source. We detect strong (∼35%) flat-topped broadband noise throughout the outburst with low characteristic frequencies (∼0.1 Hz). This makes S...
متن کاملObservations of the 599 Hz Accreting X - ray Pulsar IGR J 00291 + 5934 during the 2004 Outburst and in Quiescence
We report on optical and near-infrared observations obtained during and after the 2004 December discovery outburst of the X-ray transient and accretionpowered millisecond pulsar IGR J00291+5934. Our observations monitored the evolution of the brightness and the spectral properties of IGR J00291+5934 during the outburst decay towards quiescence. We also present optical, near-infrared and Chandra...
متن کاملA Frequency Glitch in an Accreting Pulsar
Frequency glitches have been observed so far only in radio pulsars and anomalous X-ray pulsars. Here we present evidence of a glitch in a neutron star accreting from a Be companion. The transient KS 1947+300 reappeared in 2000 October as a moderately strong X-ray source that exhibited 18.7 s pulsations, leading to an identification with the BATSE source GRO J1948+32, last detected in 1994. We h...
