    Cooling of magnetars with internal layer heating

    We model thermal evolution of magnetars with a phenomenological heat source in a spherical internal layer and compare the results with observations of persistent thermal radiation from magnetars. We show that...

    Does mass accretion lead to field decay in neutron stars?

    WHETHER or not neutron-star magnetic fields decay is a matter of current debate. The recent observation1,2 of cyclotron lines from γ-ray-burst sources, thought to be relatively old neutron stars, indicates that ...

    Quasi-periodic oscillations in bright galactic-bulge X-ray sources

    Quasi-periodic oscillations with frequencies in the range 5–50 Hz have recently been discovered in X-rays from two bright galactic-bulge sources and ScoX-1. We propose that these sources are weakly magnetic ne...

    Spin-down episode of the X-ray pulsar Vela X-1

    Since the discovery1 of a 283-s pulsation of an X-ray binary Vela X-1, several observations2–8 between 1975 and 1978 have revealed that its pulse period P was decreasing with an average value of Ṗ/P ≍ −1.5 × 10−4

    A new mode of X-ray bursts from MXB1730–335

    We report here on the unusual behaviour of MXB1730–335, the rapid burster1 as observed by the X-ray astronomy satellite Hakucho between 8 and 22 August 19792. MXB1730–335 is a unique burst source which generates ...
