Fitting strategies of accretion column models and application to the broadband spectrum of Cen X-3
Philipp Thalhammer, Matthias Bissinger, Ralf Ballhausen +10
Due to the complexity of modeling the radiative transfer inside the accretion columns of neutron star binaries, their X-ray spectra are still commonly described with phenomenologic…
The giant outburst of 4U 0115+634 in 2011 with Suzaku and RXTE
Matthias Bissinger né Kühnel, Ingo Kreykenbohm, Carlo Ferrigno +19
We present an analysis of X-ray spectra of the high mass X-ray binary 4U 0115+634 as observed with Suzaku and RXTE in 2011 July, during the fading phase of a giant X-ray outburst.…
Spectral and Timing Analysis of the accretion-powered pulsar 4U 1626-67 observed with Suzaku and NuSTAR
Wataru B. Iwakiri, Katja Pottschmidt, Sebastian Falkner +13
We present an analysis of the spectral shape and pulse profile of the accretion-powered pulsar 4U 1626-67 observed with Suzaku and NuSTAR during a spin-up state. The pulsar, which…
Multiple cyclotron line-forming regions in GX 301-2
F. Fuerst, S. Falkner, D. Marcu-Cheatham +6
We present two observations of the high-mass X-ray binary GX 301-2 with NuSTAR, taken at different orbital phases and different luminosities. We find that the continuum is well des…
A precessing Be disk as a possible model for occultation events in GX 304-1
Matthias Kühnel, Richard E. Rothschild, Atsuo T. Okazaki +14
We report on the RXTE detection of a sudden increase in the absorption column density, , during the 2011 May outburst of GX 304-1. The increased up to…
The NuSTAR X-ray Spectrum of Hercules X-1: A Radiation-Dominated Radiative Shock
Michael T. Wolff, Peter A. Becker, Amy M. Gottlieb +7
We report new spectral modeling of the accreting X-ray pulsar Hercules X- 1. Our radiation-dominated radiative shock model is an implementation of the analytic work of Becker & Wol…
The Transient Accereting X-Ray Pulsar XTE J1946+274: Stability of the X-Ray Properties at Low Flux and Updated Orbital Solution
Diana M. Marcu-Cheatham, Katja Pottschmidt, Matthias Kühnel +19
We present a timing and spectral analysis of the X-ray pulsar XTE J1946+274 observed with Suzaku during an outburst decline in 2010 October and compare with previous results. XTE J…
