The accretion powered spin-up of GRO J 1750 − 27

The timing properties of the 4.45 s pulsar in the Be X-ray bina ry system GRO J1750 −27 are examined using hard X-ray data from INTEGRALandSwiftduring a Type II outburst observed during 2008. The orbital parameters of the system are measur d and agree well with those found during the last known outburst of the system in 1995. Co rrecting the effects of the… CONTINUE READING
