Accretion-powered Millisecond Pulsar Outbursts
The population of accretion-powered millisecond pulsars (AMSPs) has grown rapidly over the last four years, with the discovery of six new examples to bring the total sample to seven. While the first six discovered are transients active for a few weeks every two or more years, the most recently-discovered source HETE J1900.1−2455, has been active for more than 8 months. We summarise the transien...
متن کاملWhat Makes an Accretion-Powered Millisecond Pulsar?
We investigate the dependence of pulse amplitudes of accreting millisecond pulsars on the masses of the neutron stars. Because the pulsation amplitudes are suppressed as the neutron stars become more massive, the probability of detection of pulsations decreases in systems that have been accreting for a long time. However, the probability of detectable pulsations is higher in transient systems w...
متن کاملMulti-wavelength Emissions from the Millisecond Pulsar Binary Psr J1023+0038 during an Accretion Active State
Recent observations strongly suggest that the millisecond pulsar binary PSR J1023+0038 has developed an accretion disk since 2013 June. We present a multi-wavelength analysis of PSR J1023+0038, which reveals that 1) its gamma-rays suddenly brightened within a few days in June/July 2013 and has remained at a high gamma-ray state for several months; 2) both UV and X-ray fluxes have increased by r...
متن کاملNon-linear resonance in the accretion disk of a millisecond pulsar
Twin quasi-periodic millisecond modulations of the X-ray flux (kHz QPOs) have recently been reported from an accreting 2.5 ms X-ray pulsar. We identify modes of disk oscillations whose frequencies are in agreement with the observed ones when the rotating neutron star is modeled with realistic equations of state. The frequency difference of the twin QPOs, equal to about one half of the neutron-s...
متن کاملThe Disk-Magnetosphere Interaction in the Accretion-Powered Millisecond Pulsar SAXJ1808.4–3658
The recent discovery of the first known accretion-powered millisecond pulsar with the Rossi X-Ray Timing Explorer allows the first direct test of models for the interaction of the accretion disk and the magnetic field of weakly magnetic (B ∼< 10 10 G) neutron stars in X-ray binaries. The simple Ṁ3/7 scaling law for the Keplerian frequency at the magnetic interaction radius, widely used to model...
