The Physics of Accretion Onto Highly Magnetized Neutron Stars
Michael T. Wolff, Peter A. Becker, Joel Coley +16
Studying the physical processes occurring in the region just above the magnetic poles of strongly magnetized, accreting binary neutron stars is essential to our understanding of st…
Evidence for different accretion regimes in GRO J1008-57
Matthias Kühnel, Felix Fürst, Katja Pottschmidt +6
We present a comprehensive spectral analysis of the BeXRB GRO J1008-57 over a luminosity range of three orders of magnitude using NuSTAR, Suzaku and RXTE data. We find significant…
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…
EXO 2030+375 Restarts in Reverse
Peter Kretschmar, Felix Fuerst, Colleen A. Wilson-Hodge +8
The Be X-ray binary pulsar EXO 2030+375, first detected in 1985, has shown a significant detected X-ray outburst at nearly every periastron passage of its 46-day orbit for the past…
Simultaneous fits in ISIS on the example of GRO J1008-57
Matthias Kühnel, Sebastian Müller, Ingo Kreykenbohm +9
Parallel computing and steadily increasing computation speed have led to a new tool for analyzing multiple datasets and datatypes: fitting several datasets simultaneously. With thi…
The Goodness of Simultaneous Fits in ISIS
Matthias Kühnel, Sebastian Falkner, Christoph Grossberger +15
In a previous work, we introduced a tool for analyzing multiple datasets simultaneously, which has been implemented into ISIS. This tool was used to fit many spectra of X-ray binar…
Suzaku observations of the 2013 outburst of KS 1947+300
Ralf Ballhausen, Matthias Kühnel, Katja Pottschmidt +9
We report on the timing and spectral analysis of two Suzaku observations with different flux levels of the high-mass X-ray binary KS 1947+300 during its 2013 outburst. In agreement…
The reawakening of the sleeping X-ray pulsar XTE J1946+274
Sebastian Müller, Matthias Kühnel, Isabel Caballero +9
We report on a series of outbursts of the high mass X-ray binary XTE J1946+274 in 2010/2011 as observed with INTEGRAL, RXTE, and Swift. We discuss possible mechanisms resulting in…
A Suzaku View of Cyclotron Line Sources and Candidates
K. Pottschmidt, S. Suchy, E. Rivers +20
Seventeen accreting neutron star pulsars, mostly high mass X-ray binaries with half of them Be-type transients, are known to exhibit Cyclotron Resonance Scattering Features (CRSFs)…
