Timing of accreting millisecond pulsars

摘要：

We review recent results from the X-ray timing of accreting millisecond pulsars in LMXBs. This is the first time a timing analysis is performed on accreting millisecond pulsars, and for the first time we can obtain information on the behavior of a very fast pulsar subject to accretion torques. We find both spin-up and spin-down behaviors, from which, using available models for the accretion torques, we derive information on the mass accretion rate and magnetic field of the neutron star in these systems. We also report here the first measure of the orbital period derivative for an accreting millisecond pulsar, derived for SAX J1808.4-3658 over a timespan of more 7 years.
