A possible phase dependent absorption feature in the transient X-ray pulsar SAX J2103.5+4545
McKinley C. Brumback, Ryan C. Hickox, Felix S. Fürst +5
We present an X-ray spectral and timing analysis of two observations of the transient Be X-ray binary SAX J2103.5+4545 during its April 2016 outburst, which was characteri…
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…
Studying the accretion geometry of EXO 2030+375 at luminosities close to the propeller regime
F. Fuerst, P. Kretschmar, J. J. E. Kajava +10
The Be X-ray binary EXO 2030+375 was in an extended low luminosity state during most of 2016. We observed this state with NuSTAR and Swift, supported by INTEGRAL observations as we…
Looking at A 0535+26 at low luminosities with NuSTAR
Ralf Ballhausen, Katja Pottschmidt, Felix Fürst +12
We report on two NuSTAR observations of the HMXB A 0535+26 taken toward the end of its normal 2015 outburst at very low keV luminosities of erg/s an…
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…
