SLX 1732 - 304 in the Globular Cluster

The X - ray Source SLX 1732 - 304 in the Globular Cluster Terzan 1 : The Spectral States and an X - ray Burst

A Chandra observation of the globular cluster Terzan 1 : the neutron - star X - ray transient X 1732 – 304 in quiescence

We present a short (∼3.6 ks) Chandra/HRC-I observation of the globular cluster Terzan 1. This cluster is known to contain the bright neutron star low-mass X-ray binary X 1732–304 which was active during the 1980’s and most of the 1990’s. During our observation, we detect one source with a 0.5–10 keV luminosity of approximately 1 − 2× 10 erg s−1 (for an assumed distance of 5.2 kpc). However, its...

There exists a group of persistently faint galactic X-ray sources that, based on their location in the galaxy, high Lx/Lopt, association with X-ray bursts, and absence of low frequency Xray pulsations, are thought to be low-mass X-ray binaries (LMXBs). We present results from Chandra observations for eight of these systems: 4U 1708–408, 2S 1711–339, KS 1739–304, SLX 1735–269, GRS 1736–297, SLX ...

A Chandra X - ray observation of the globular cluster

We present a ∼19 ks Chandra ACIS-S observation of the globular cluster Terzan 1. Fourteen sources are detected within 1.4 of the cluster center with 2 of these sources predicted to be not associated with the cluster (background AGN or foreground objects). The neutron star X-ray transient, X1732−304, has previously been observed in outburst within this globular cluster with the outburst seen to ...

A Chandra X - ray observation of the globular cluster Terzan 1

We present a ∼19-ks Chandra Advanced CCD Imaging Spectrometer (ACIS)-S observation of the globular cluster Terzan 1. 14 sources are detected within 1.4 arcmin of the cluster centre with two of these sources predicted to be not associated with the cluster (background active galactic nuclei or foreground objects). The neutron star X-ray transient, X1732−304, has previously been observed in outbur...
