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…
Cyclotron resonant scattering feature simulations. II. Description of the CRSF simulation process
F. -W. Schwarm, R. Ballhausen, S. Falkner +12
Cyclotron resonant scattering features (CRSFs) are formed by scattering of X-ray photons off quantized plasma electrons in the strong magnetic field (of the order 10^12 G) close to…
Formation of phase lags at the cyclotron energies in the pulse profiles of magnetized, accreting neutron stars
G. Schönherr, F. -W. Schwarm, S. Falkner +13
Context: Accretion-powered X-ray pulsars show highly energy-dependent and complex pulse-profile morphologies. Significant deviations from the average pulse profile can appear, in p…
GRO J1008-57: an (almost) predictable transient X-ray binary
M. Kühnel, S. Müller, I. Kreykenbohm +13
A study of archival RXTE, Swift, and Suzaku pointed observations of the transient high mass X-ray binary GRO J1008-57 is presented. A new orbital ephemeris based on pulse arrival t…
No anti-correlation between cyclotron line energy and X-ray flux in 4U 0115+634
Sebastian Müller, Carlo Ferrigno, Matthias Kühnel +18
We report on an outburst of the high mass X-ray binary 4U 0115+63 with a pulse period of 3.6s in 2008 March/April as observed with RXTE and INTEGRAL. During the outburst the neutro…
Spectral Formation in Accreting X-Ray Pulsars: Bimodal Variation of the Cyclotron Energy with Luminosity
P. A. Becker, D. Klochkov, G. Schonherr +7
Accretion-powered X-ray pulsars exhibit significant variability of the Cyclotron Resonance Scattering Feature (CRSF) centroid energy on pulse-to-pulse timescales, and also on much…
