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…

Constraining compactness and magnetic field geometry of X-ray pulsars from the statistics of their pulse profiles
Marja Annala, Juri Poutanen
The light curves observed from X-ray pulsars and magnetars reflect the radiation emission pattern, the geometry of the magnetic field, and the neutron star compactness. We study th…

On the nature of pulse profile variations and timing noise in accreting millisecond pulsars
Juri Poutanen, Askar Ibragimov, Marja Annala
Timing noise in the data on accretion-powered millisecond pulsars (AMP) appears as irregular pulse phase jumps on timescales from hours to weeks. A large systematic phase drift is…
