Physical modeling of viscous disc evolution around magnetized neutron star. Aql X-1 2013 outburst decay
Galina Lipunova, Konstantin Malanchev, Sergey Tsygankov +3
We present a model of a viscously evolving accretion disc around a magnetized neutron star. The model features the varying outer radius of the hot ionized part of the disc due to c…
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…
