14 Jan 2015 | | Abstract: | As of 2014 August, the Nuclear Spectroscopic Telescope Array (NuSTAR) had
observed ~30 X-ray binaries either as part of the planned program, as targets
of opportunity, or for instrument calibration. The main science goals for the
observations include probing the inner part of the accretion disk and
constraining black hole spins via reflection components, providing the first
observations of hard X-ray emission from quiescent Low Mass X-ray Binaries
(LMXBs), measuring cyclotron lines from accreting pulsars, and studying type I
X-ray bursts from neutron stars. Here, we describe the science objectives in
more depth and give an overview of the NuSTAR observations that have been
carried out to achieve the objectives. These include observation of four "IGR"
High Mass X-ray Binaries (HMXBs) discovered by INTEGRAL. We also summarize the
results that have been obtained and their implications. Among the IGR HMXBs, we
focus on the discovery of a cyclotron line in the spectrum of IGR J17544-2619. | | Source: | arXiv, 1501.3534 | | Services: | Forum | Review | PDF | Favorites | |
