Re-estimating the Spin Parameter of the Black Hole in Cygnus X-1
Xueshan Zhao, Lijun Gou, Yanting Dong +6
Cygnus X-1 is a well-studied persistent black hole X-ray binary. Recently, the three parameters needed to estimate the black hole spin of this system, namely the black hole mass $M…
Cygnus X-1 contains a 21-solar mass black hole -- implications for massive star winds
James C. A. Miller-Jones, Arash Bahramian, Jerome A. Orosz +23
The evolution of massive stars is influenced by the mass lost to stellar winds over their lifetimes. These winds limit the masses of the stellar remnants (such as black holes) that…
A detailed study on the reflection component for the Black Hole Candidate MAXI J1836-194
Yanting Dong, Javier A. García, Zhu Liu +3
We present a detailed spectral analysis of the black hole candidate MAXI J1836-194. The source was caught in the intermediate state during its 2011 outburst by Suzaku and RXTE. We…
Spectral evidence of an accretion disk in wind-fed X-ray pulsar Vela X-1 during an unusual spin-up period
Zhenxuan Liao, Jiren Liu, Xueying Zheng +1
In classical supergiant X-ray binaries (SgXBs), the Bondi-Hoyle-Lyttleton wind accretion was usually assumed, and the angular momentum transport to the accretors is inefficient. Th…
The spatial distribution of circumstellar material of the wind-fed system GX 301-2
Xueying Zheng, Jiren Liu, Lijun Gou
The distribution of the circumstellar material in systems of supergiant X-ray binaries (SgXBs) is complex and not well probed observationally. We report a detailed study of the spa…
