TL;DR: In this article, a comparison between the most recent outburst of IGRJ16479-4514, caught by Swift on 29 January 2009 and those detected previously from this source was carried out.

TL;DR: In this paper, a shot noise model was developed to test the presence of a coupling between the periodic and aperiodic variability of X-ray pulsars, and the model power spectrum was fitted to the power spectra of three x-ray pulses, Vela X-1, 4U 1145-62, and Cen X-3, observed with EXOSAT.

TL;DR: In this article, the authors derived an upper limit on the spin-period derivative of a binary system in which a massive white dwarf accretes from a hot subdwarf companion, the bright sdO star HD 49798.

TL;DR: In this article, a systematic search for periodic signals in a sample of ROSAT PSPC light curves was conducted, and the authors discovered 8.9 s X-ray pulsations in 2E 0050.1-7247, a variable Xray source in the Small Magellanic Cloud.

TL;DR: In this article, the results from two BeppoSAX observations of the Z source GX 349+2 performed in 2001 February and covering the broad energy range 0.12-200 keV were reported.
