A millisecond pulsar in an x-ray binary system
Article Abstract:
A transient X-ray source designated XTE J1808-369 has been recently been detected by the Rossi X-ray Timing Explorer (RXTE). A series of fast Fourier transforms were performed and clear evidence for X-ray pulsations with a frequency close to 401.0 Hz in the power-density spectrum were discovered. the initial, 2-h RXTE observing span is reported, and it is thought that XTE J1808-369 is a weak, transient X-ray source, possibly the first example of a type of millisecond radio pulsar progenitor.

The two-hour orbit of a binary millisecond X-ray pulsar
Article Abstract:
Coherent X-ray pulsations having a millisecond period from a suspected low-mass X-ray binary system, have recent been detected. Observations have shown that the orbital period of the binary system is two hours, establishing it as a low-mass X-ray binary (LMXB) system. An apparent modulation of the X-ray flux at the orbital period is also found. The system appears to be closely inked to the 'black-widow' millisecond radio pulsars.

Nuclear-powered millisecond pulsars and the maximum spin frequency of neutron stars
Article Abstract:
Research indicates that the burst oscillations of an accreting millisecond pulsar or a neutron star, exhibit the same rotational phase, suggesting that the oscillations are nuclear-powered pulsations tracing the spin of accreting neutron stars. Data point out that gravitational radiation losses lare capable of limiting accretion torques in spinning up neutron stars.
