Abstract
The discovery of quasi-periodic oscillations (QPOs) in the X-ray flux from the recurrent transient X-ray pulsar V0332+53 is reported. The ce ntroid frequency, full width at half-maximum (FWHM), and the relative root mean square (rms) amplitude of the QPOs are (5.1 +/- 0.5) x 10(-2 ) Hz, (3.3 +/- 1.5) x 10(-2) Hz, and 4.8% +/- 1.2%, respectively. The beat frequency model is tested using these results and previously repo rted QPOs from other X-ray binary pulsars.
