29 Jun 2011 | Abstract: | We have re-analyzed archival RXTE data of the X-ray binary Cygnus X-3 with a
view to investigate the timing properties of the source. As compared to
previous studies, we use an extensive sample of observations that include all
the radio/X-ray spectral states that have been categorized in the source
recently. In this study we identify two additional instances of Quasi-Periodic
Oscillations that have centroid frequencies in the mHz regime. These events are
all associated to a certain extent with major radio flaring, that in turn is
associated with relativistic jet ejection events. We review briefly scenarios
whereby the Quasi-Periodic Oscillations may arise. | Source: | arXiv, 1106.5848 | Services: | Forum | Review | PDF | Favorites |
