Evidence for neutron star triaxial free precession in Her X-1 from Fermi/GBM pulse period measurements
Dmitry Kolesnikov, Nikolai Shakura, Konstantin Postnov
Her X-1/HZ Her is one of the best studied accreting X-ray pulsars. In addition to the pulsating and orbital periods, the X-ray and optical light curves of the source exhibit an alm…
On the nature of the 35-day cycle in HZ Her/Her X-1
N. I. Shakura, D. A. Kolesnikov, K. A. Postnov
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 the free precession of the…
Observations of Her X-1 in low states during SRG/eROSITA all-sky survey
N. I. Shakura, D. A. Kolesnikov, P. S. Medvedev +4
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…
Modeling of 35-day superorbital cycle of and light curves of IMXB HZ Her/Her X-1
D. A. Kolesnikov, N. I. Shakura, K. A. Postnov +13
The X-ray binary Her X-1 consists of an accreting neutron star and the optical component HZ Her. The 35-day X-ray superorbital variability of this system is known since its discove…
Galactic population of black holes in detached binaries with low-mass stripped helium stars: the case of LB-1 (LS~V+22~25)
L. R. Yungelson, A. G. Kuranov, K. A. Postnov +1
We model the Galactic population of detached binaries that harbor black holes with (0.5-1.7) solar mass companions -- the remnants of case B mass-exchange that rapidly cross Hertzs…
