Millisecond pulsar
Discovery of kilohertz quasi periodic oscillations and shifted frequency correlations in the accreting millisecond pulsar XTE J1807 294
... We report the discovery of twin kHz QPOs in the X ray flux of XTE J1807– 294, the fourth accreting millisecond pulsar (AMP). This is the second AMP exhibiting twin kHz QPOs. In contrast to the first case, ...
