Quest for quiescent neutron star low mass X-ray binaries in the Small Magellanic CloudChowdhury, Md. Mizanul Huq 06 1900 (has links)
We present the first spectral search for neutron stars (NSs) in low-mass X-ray
binaries (LMXBs) between outbursts in the Small Magellanic Cloud (SMC).
We identify and discuss candidate LMXBs in quiescence in the SMC using
deep Chandra X-ray observations of two portions of the SMC. We produce
X-ray color-magnitude-diagrams of XRSs of these two fields and identify 10
candidates for quiescent NS LMXBs. Spectral fitting and searches for optical
counterparts rule out five, leaving five candidate quiescent NS LMXBs.
We estimate that we are sensitive to ~10% of quiescent NS LMXBs in our
fields. Our fields include 4.410^7 M of stellar mass, giving an upper limit of 10^{6} LMXBs per M in the SMC. We place a lower limit on the average duty cycle of NS LMXBs as ~0.003.
