SAX J1808.4-3658: high resolution spectroscopy and decrease of pulsed fraction at low energies
Alessandro Patruno, Nanda Rea, Diego Altamirano +3
XMM-Newton observed the accreting millisecond pulsar SAX J1808.4-3658 during its 2008 outburst. We present timing and spectral analyses of this observation, in particular the first…
Broad relativistic iron emission line observed in SAX J1808.4-3658
E. M. Cackett, D. Altamirano, A. Patruno +4
During the September-October 2008 outburst of the accreting millisecond pulsar SAX J1808.4-3658, the source was observed by both Suzaku and XMM-Newton approximately 1 day apart. Sp…
A decade of timing an accretion-powered millisecond pulsar: The continuing spin down and orbital evolution of SAX J1808.4-3658
J. M. Hartman, A. Patruno, D. Chakrabarty +4
The Rossi X-ray Timing Explorer has observed five outbursts from the transient 2.5 ms accretion-powered pulsar SAX J1808.4-3658 during 1998-2008. We present a pulse timing study of…
Motion of the hot spot and spin torque in accreting millisecond pulsars
Alessandro Patruno
The primary concern of this contribution is that accreting millisecond pulsars (AMXPs) show a much larger amount of information than is commonly believed. The three questions to be…
Chandra and XMM-Newton observations of the low-luminosity X-ray pulsators SAX J1324.4-6200 and SAX J1452.8-5949
Ramanpreet Kaur, Rudy Wijnands, Alessandro Patruno +5
We present results from our Chandra and XMM-Newton observations of two low-luminosity X-ray pulsators SAX J1324.4-6200 and SAX J1452.8-5949 which have spin-periods of 172 s and 437…
A New Class of Radio Pulsars - Back in 1982
M. Ali Alpar
Basic ideas about the torques on the neutron star and the existence of an equilibrium rotation period followed from the recognition that most X-ray binaries contain accretion power…
