Evidence for crust cooling in the transiently accreting 11-Hz X-ray pulsar in the globular cluster Terzan 5
globular clusters: individual (Terzan 5) - X-rays: binaries - stars: neutron -pulsars: individual (CXOGClb J174804.8–244648, IGR J17480–2446)

The temporal heating and subsequent cooling of the crusts of transiently accreting neutron stars carries unique information about their structure and a variety of nuclear reaction processes. We report...
Pulse-amplitude-resolved spectroscopy of bright accreting pulsars: indication of two accretion regimes
X-ray binaries – neutron stars – accretion
2011/10/8
Context: In addition to coherent pulsation, many accreting neutron stars exhibit flaring activity and strong aperiodic variability on time scales comparable to or shorter than their pulsation period. ...
Orbital Evolution Measurement of the Accreting Millisecond X-ray Pulsar SAX J1808.4–3658
Stars neutron stars—pulsars individual (SAX J1808.4–3658) magnetic fields—X-rays binaries—accretion

We present results from a pulse timing analysis of the
accretion-powered millisecond X-ray pulsar SAX J1808.4–3658 using
X-ray data obtained during four outbursts of this source. Extensive observati...
