  • We report the discovery of a new quasi-periodic oscillation (QPO) at 0.22 Hz, centered on the source spin frequency of the high-mass X-ray binary system V0332 + 53 when the source was observed during its 2004 November/2005 March outburst by RXTE. In addition to this new QPO, we also detected the known 0.05 Hz QPO. Both the 0.22 and 0.05 Hz QPOs stand out clearly at a midflux level of the outburst during 2005 January 15 - 19, and later at an even lower flux level as the width of the 0.22 Hz QPO… CONTINUE READING
