Linking Burst-only X–ray Binary Sources to Faint X–ray Transients
نویسنده
چکیده
Burst-only sources are X–ray sources showing up only during short bursts but with no persistent emission (at least with the monitoring instrument which led to their discovery). These bursts have spectral characteristics consistent with thermonuclear (type I) burst from the neutron star surface, linking burst-only sources to neutron star X–ray binary transients. We have carried out a series of snapshot observations of the entire sample of burstonly sources with the Swift satellite. We found a few sources in outburst and detect faint candidates likely representing their quiescent counterparts. In addition, we observed three quasi-persistent faint X–ray binary transients. Finally we discuss burst-only sources and quasi-persistent sources in the framework of neutron star transients.

Forty Years of X-Ray Binaries
In 2012 it was forty years ago that the discovery of the first X-ray binary Centaurus X-3 became known. That same year it was discovered that apart from the High-Mass X-ray Binaries (HMXBs) there are also Low-Mass X-ray Binaries (LMXBs), and that Cygnus X-1 is most probably a black hole. By 1975 also the new class of Be/X-ray binaries was discovered. After this it took 28 years before ESAs INTE...
متن کاملX-ray Transients from X-ray Binaries to Gamma Ray Bursts
We discuss three classes of x-ray transients to highlight three new types of transients found with the Wide Field Cameras onboard BeppoSAX. First there are the transients related to Low Mass X-ray Binaries in outburst, typically lasting weeks to months and reaching luminosities of the Eddington limit for a few solar masses. Recently another subclass of outbursts in such binaries has been discov...
متن کاملThe XMM - Newton / Chandra monitoring campaign of the Galactic center region
We present the first results of our X-ray monitoring campaign on a 1.7 square degree region centered on Sgr A* using the satellites XMM-Newton and Chandra. The purpose of this campaign is to monitor the behavior (below 10 keV) of X-ray sources (both persistent and transient) which are too faint to be detected by monitoring instruments aboard other satellites currently in orbit (e.g., Rossi X-ra...

From October 1999 to August 2002, 45 transient X-ray sources were detected in M31 by Chandra and XMM-Newton. We have performed spectral analysis of all XMM-Newton and Chandra ACIS detections of these sources, as well as flux measurements of Chandra HRC detections. The result is absorption-corrected Xray lightcurves for these sources covering this 2.8 year period, along with spectral parameters ...
متن کاملGRB060602B = Swift J1749.4-2807: an unusual transiently accreting neutron-star X-ray binary
We present an analysis of the Swift Burst Alert Telescope (BAT) and X-ray telescope (XRT) data of GRB060602B, which is most likely an accreting neutron star in a binary system and not a gamma-ray burst. Our analysis shows that the BAT burst spectrum is consistent with a thermonuclear flash (type I X-ray burst) from the surface of an accreting neutron star in a binary system. The X-ray binary na...
