  • Orbit and intrinsic spin-up... Orbit and intrinsic spin-up of the newly discovered transient X-ray pulsar Swift J0243.6+6124
    Doroshenko, V.; Tsygankov, S.; Santangelo, A. Astronomy and astrophysics (Berlin), 05/2018, Letnik: 613
    Journal Article
    Recenzirano
    Odprti dostop

    We present the orbital solution for the newly discovered transient Be X-ray binary Swift J0243.6+6124 based on the data from the gamma-ray burst monitor on board Fermi obtained during the October ...

  • Propeller effect in action ... Propeller effect in action in the ultraluminous accreting magnetar M82 X−2
    Tsygankov, Sergey S; Mushtukov, Alexander A; Suleimanov, Valery F ... Monthly notices of the Royal Astronomical Society, 03/2016, Letnik: 457, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    We present here the first convincing observational manifestation of a magnetar-like magnetic field in an accreting neutron star in binary system – the first pulsating ultraluminous X-ray source X−2 ...

  • The critical accretion lumi... The critical accretion luminosity for magnetized neutron stars
    Mushtukov, Alexander A; Suleimanov, Valery F; Tsygankov, Sergey S ... Monthly notices of the Royal Astronomical Society, 02/2015, Letnik: 447, Številka: 2
    Journal Article
    Recenzirano
    Odprti dostop

    The accretion flow around X-ray pulsars with a strong magnetic field is funnelled by the field to relatively small regions close to the magnetic poles of the neutron star (NS), the hotspots. During ...

  • On the maximum accretion lu... On the maximum accretion luminosity of magnetized neutron stars: connecting X-ray pulsars and ultraluminous X-ray sources
    Mushtukov, Alexander A; Suleimanov, Valery F; Tsygankov, Sergey S ... Monthly notices of the Royal Astronomical Society, 12/2015, Letnik: 454, Številka: 3
    Journal Article
    Recenzirano
    Odprti dostop

    We study properties of luminous X-ray pulsars using a simplified model of the accretion column. The maximal possible luminosity is calculated as a function of the neutron star (NS) magnetic field and ...

  • Optically thick envelopes a... Optically thick envelopes around ULXs powered by accreating neutron stars
    Mushtukov, Alexander A; Suleimanov, Valery F; Tsygankov, Sergey S ... Monthly notices of the Royal Astronomical Society, 05/2017, Letnik: 467, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    Abstract Magnetized neutron stars power at least some ultraluminous X-ray sources. The accretion flow in these cases is interrupted at the magnetospheric radius and then reaches the surface of a ...

  • Spectrum formation in X-ray... Spectrum formation in X-ray pulsars at very low mass accretion rate: Monte Carlo approach
    Mushtukov, Alexander A; Suleimanov, Valery F; Tsygankov, Sergey S ... Monthly notices of the Royal Astronomical Society, 04/2021, Letnik: 503, Številka: 4
    Journal Article
    Recenzirano
    Odprti dostop

    ABSTRACT Recently, it has been discovered that the transition of X-ray pulsars to the low luminosity state ($L\lesssim 10^{35}\, {\rm erg\ \rm s^{-1}}$) is accompanied by a dramatic spectral change. ...

    Tsygankov, Sergey S; Doroshenko, Victor; Mushtukov, Alexander A ... Monthly notices of the Royal Astronomical Society, 09/2018, Letnik: 479, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    Abstract We report on the monitoring of the final stage of the outburst from the first Galactic ultraluminous X-ray pulsar Swift J0243.6+6124, which reached ∼40 Eddington luminosities. The main aim ...

  • Constraints on the magnetic... Constraints on the magnetic field structure in accreting compact objects from aperiodic variability
    Mönkkönen, Juhani; Tsygankov, Sergey S; Mushtukov, Alexander A ... Monthly notices of the Royal Astronomical Society, 07/2022, Letnik: 515, Številka: 1
    Journal Article
    Recenzirano
    Odprti dostop

    ABSTRACT We investigate the aperiodic variability for a relatively large sample of accreting neutron stars and intermediate polars, focusing on the properties of the characteristic break commonly ...
