    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 ...

    Does supernova 1987A contain a rapidly vibrating neutron star?

    IF the recently reported1,2 0.5-ms-period pulsed optical signal from the direction of supernova 1987A originated in a young neutron star, its interpretation as a rotational period has difficulties. The surface ma...

    Low-energy Galactic-Centre γ-rays from low-mass X-ray binaries

    The hard X-ray and low-energy γ-ray emission from the Galactic Centre region (GCR) has four components1,2: a power-law continuum between 20/50 keV and 200/300 keV with inverse power-law photon index a in the rang...

    Nature and evolution of the eclipsing millisecond binary pulsar PSR1957 + 20

    A millisecond pulsar may be able to evaporate a very light companion by a particular component of its energetic radiation1–3. Pulsar turn-on in the binary follows a stage of mass transfer in a very low-mass X-ray...

    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...

    A new class of radio pulsars

    Sufficiently low magnetic field neutron stars which accrete for long times from a surrounding keplerian disk can be spun up to millisecond periods. After accretion ceases, such stars could become isolated or b...

    A processing ring model for SS433

    THE wavelengths of the shifted optical lines in SS433 seem to show a periodic variability at a period of 160 ± 3 d (or a multiple integer thereof)1,2. We have suggested that such periodicity could arise if the li...

    SS433—a massive black hole?

    THE peculiar emission line object SS433 has recently been the subject of interest following new spectrophotometric observations by Margon et al.1, and previous suggestions identifying it with the supernova remnan...
