    Evaporation of Companions in VLMXBs and in Binary Millisecond Pulsars

    The principles underlying the process of formation of a wind from a stellar atmosphere by external heating are applied to binary companions of neutron stars (NSs) which are being heated by radiation from the N...

    A New Mechanism for Angular Momentum Loss in Very-Low-Mass X-ray Binaries and Binary Millisecond Pulsars

    It is suggested that in some Low-Mass X-Ray Binaries and Millisecond Pulsar Binaries, companion winds that are excited by the radiation from the neutron star form only through the combined action of the radiat...

    Companion Winds Excited by Neutron Star Radiation in LMXBs and Millisecond Pulsars

    The lecture first describes the basic principles underlying formation of a wind from a stellar atmosphere by external heating. These ideas are then applied to the case of binary companions of neutron stars (NS...

    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...

    A Model of Pulsar Timing Noise

    We propose that the pulsar timing noise results from the magnetospheric fluctuations and internal superfluid unpinning. In general, the pulsar timing noise power spectra of frequency derivation contains two co...

    Low Energy Galactic Center Gamma Rays from Low Mass X-Ray Binaries

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

    Pulsar Turn-On and Secondary Evaporation in the PSR 1957 + 20 Binary

    A millisecond pulsar spun up in an accreting low mass X-ray binary is expected to turn on suddenly when the mass accretion rate falls below a critical value (~ 1016 gs-1). The consequent energetic radiation from ...

    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...
