The key contribution of the discovery of nuclear‐powered pulsations from the accretion‐powered millisecond pulsars (AMPs) has been the establishment of burst oscillation frequency as a reliable proxy for stellar spin rate. This has doubled the sample of rapidly‐rotating accreting neutron stars and revealed the unexpected absence of any stars rotating near the break‐up limit. The resulting ‘braking problem’ is now a major concern for theorists, particularly given the possible role of…

DISCOVERY OF BURST OSCILLATIONS IN THE INTERMITTENT ACCRETION-POWERED MILLISECOND PULSAR HETE J1900.1-2455

We report the discovery of burst oscillations from the intermittent accretion-powered millisecond pulsar (AMP) HETE J1900.1-2455, with a frequency ∼1 Hz below the known spin frequency. The burst

THE LUMINOSITY AND ENERGY DEPENDENCE OF PULSE PHASE LAGS IN THE ACCRETION-POWERED MILLISECOND PULSAR SAX J1808.4−3658

A study of the 2.5 ms accretion-powered pulsar SAX J1808.4-3658, it is reported that the magnitude of these lags is strongly dependent on the accretion rate, and the turnover suggests that the source is observing the source transitioning into the "propeller" accretion regime.

New Views of Thermonuclear Bursts

Introduction Many accreting neutron stars erupt in spectacular thermonuclear conflagrations every few hours to days. These events, known as Type I X-ray bursts, or simply X-ray bursts, are the
