Millisecond Pulsars in X-Ray Binaries
Despite considerable evidence verifying that millisecond pulsars are spun up through sustained accretion in low-mass X-ray binaries (LMXBs), it has proven surprisingly difficult to actually detect millisecond X-ray pulsars in LMXBs. There are only 5 accretion-powered millisecond X-ray pulsars known among more than 80 LMXBs containing neutron stars, but there are another 11 “nuclear-powered” mil...
متن کاملRadio ejection in the evolution of X-ray binaries: the bridge between low mass X-ray binaries and millisecond pulsars
We present a scenario for the spin-up and evolution of binary millisecond pulsars. This can explain the observational properties of the recently discovered binary millisecond pulsar PSR J1740-5340, with orbital period 32.5 hrs, in the Globular Cluster NGC 6397. The optical counterpart of this system is a star as luminous as the cluster turnoff stars, but with a lower Teff (a larger radius) whic...
متن کاملLow-mass X-ray Binaries, Millisecond Radio Pulsars, and the Cosmic Star Formation Rate
We report on the implications of the peak in the cosmic star-formation rate (SFR) at redshift z ≈ 1.5 for the resulting population of low-mass X-ray binaries(LMXB) and for that of their descendants, the millisecond radio pulsars (MRP). Since the evolutionary timescales of LMXBs, their progenitors, and their descendants are thought be significant fractions of the time-interval between the SFR pe...
متن کاملFormation of millisecond pulsars I. Evolution of low-mass X-ray binaries with Porb > 2 days
We have performed detailed numerical calculations of the non-conservative evolution of close binary systems with low-mass (1.0 − 2.0M⊙) donor stars and a 1.3M⊙ accreting neutron star. Rather than using analytical expressions for simple polytropes, we calculated the thermal response of the donor star to mass loss, in order to determine the stability and follow the evolution of the mass transfer....
متن کاملHard X-ray Emission From Low Mass X-ray Binaries
We report on Rossi X-ray Timing Explorer observations of four type I X-ray bursters; namely 1E1724– 3045, GS1826–238, SLX1735–269 and KS1731-260. The first three were in a low state, with 1-200 keV Xray luminosities in the range ∼ 0.05−0.1 LEdd (LEdd: Eddington luminosity for a neutron star = 2.5×10 38 ergs s), whereas KS1731-260 was in a high state with a luminosity ∼ 0.35 LEdd. The low state ...
