  • Galactic population of black holes in detached binaries with low-mass stripped helium stars: The case of LB-1 (LS V+22 25) 
    Yungelson L.R.; Kuranov A.G.; Postnov K.A.; Kolesnikov D.A. (2020)
    © 2020 The Author(s) Published by Oxford University Press on behalf of the Royal Astronomical Society. We model the Galactic population of detached binaries that harbour black holes with 0.5-1.7 M companions - remnants of ...
  • Modelling of 35-d superorbital cycle of B and V light curves of IMXB HZ Her/Her X-1 
    Kolesnikov D.A.; Shakura N.I.; Postnov K.A.; Volkov I.M.; Bikmaev I.F.; Irsmambetova T.R.; Staubert R.; Wilms J.; Irtuganov E.; Golysheva P.Y.; Shugarov S.Y.; Nikolenko I.V.; Trunkovsky E.M.; Schönherr G.; Schwope A.; Klochkov D. (2020)
    © 2020 The Author(s). The X-ray binary Her X-1 consists of an accreting neutron star and the optical component HZ Her. The 35-d X-ray superorbital variability of this system is known, since its discovery in 1972 by the ...
  • Observations of Her X-1 in low states during SRG/eROSITA all-sky survey 
    Shakura N.I.; Kolesnikov D.A.; Medvedev P.S.; Sunyaev R.A.; Gilfanov M.R.; Postnov K.A.; Molkov S.V. (2021)
    eROSITA (extended ROentgen Survey with an Imaging Telescope Array) instrument onboard the Russian-German 'Spectrum-Roentgen-Gamma' (SRG) mission observed the Her X-1/HZ Her binary system in multiple scans over the source ...
  • On the Nature of the 35-Day Cycle in HZ Her/Her X-1 
    Shakura N.I.; Kolesnikov D.A.; Postnov K.A. (2021)
    Abstract: Regular variations of the pulse period of Her X-1 with X-ray flux observed by Fermi/GBM are examined. We argue that these regular variations result from free precession of the neutron star in Her X-1.
