Varying disc-magnetosphere coupling as the origin of pulse profile variability in SAX J1808.4-3658
Jari J. E. Kajava, Askar Ibragimov, Marja Annala +2
Accreting millisecond pulsars show significant variability of their pulse profiles, especially at low accretion rates. On the other hand, their X-ray spectra are remarkably similar…

The 2009 outburst of accreting millisecond pulsar IGR J17511-3057 as observed by SWIFT and RXTE
A. Ibragimov, J. J. E. Kajava, J. Poutanen
The twelfth accretion-powered millisecond pulsar, IGR J17511-3057, was discovered in September 2009. In this work we study its spectral and timing properties during the 2009 outbur…
