NuSTAR Observations of the State Transition of Millisecond Pulsar Binary PSR
We report NuSTAR observations of the millisecond pulsar–low-mass X-ray binary (LMXB) transition system PSR J1023+0038 from 2013 June and October, before and after the formation of an accretion disk around the neutron star. Between June 10 and 12, a few days to two weeks before the radio disappearance of the pulsar, the 3–79 keV X-ray spectrum was well fit by a simple power law with a photon ind...
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 کاملProperties and Evolution of the Redback Millisecond Pulsar Binary Psr J2129–0429
PSR J2129−0429 is a “redback” eclipsing millisecond pulsar binary with an unusually long 15.2 hr orbit. It was discovered by the Green Bank Telescope in a targeted search of unidentified Fermi gamma-ray sources. The pulsar companion is optically bright (mean mR=16.6mag), allowing us to construct the longest baseline photometric data set available for such a system. We present 10 years of arch...
متن کاملDetection of pulsed X-ray emission from the binary millisecond pulsar PSR J0218+4232
We report the detection of pulsed X-ray emission from the binary millisecond pulsar PSR J0218+4232 in a 100 ks ROSAT HRI observation. The lightcurve deviates from a flat distribution at a ∼ 4.8σ level, showing a sharp main pulse with a duty cycle of ∼ 0.15 (350μs), compatible with smearing due to the scatter in the ROSAT clock calibration. The intrinsic width can be smaller than 100μs. There is...
