The low-mass X-ray binary and Z source GX 17+2 undergoes infrared K-band brightening episodes of at least 3.5 mag. The source of these episodes is not known. Prior published K-band magnitudes and new K-band measurements acquired between 2006 and 2008 suggest that the episodes last at least 4 hr and have a period of 3.01254 ± 0.00002 days. Future bright episodes can be predicted using the ephemeris JDmax(n) = 2454550.79829 + (3.01254  ±   0.00002)(n) days. A growing body of evidence suggests…

SPITZER OBSERVATIONS OF GX17+2: CONFIRMATION OF A PERIODIC SYNCHROTRON SOURCE

GX17+2 is a low-mass X-ray binary (LMXB) that is also a member of a small family of LMXBs known as “Z-sources” that are believed to have persistent X-ray luminosities that are very close to the

Infrared Photometric Variability of GX 13+1 and GX 17+2

We present infrared photometry of the Galactic bulge X-ray binary systems GX 13+1 and GX 17+2 obtained in 1997 July and August using OSIRIS on the 1.8 m Perkins Telescope at Lowell Observatory. GX

GX 17+2 : X-RAY SPECTRAL AND TIMING BEHAVIOUR OF A BURSTING Z SOURCE

We investigated the properties of the Z pattern of the low-mass X-ray binary GX 17+2 in the X-ray colour-colour diagrams (CDs) and hardness-intensity diagrams (HIDs), and of the power spectra as a

Infrared observations of low-mass X-ray binaries – I. Candidates for bright bulge sources

The first infrared imaging of bright Galactic Bulge X-ray source fields is presented. In spite of the extreme crowding in these regions, plausible candidates for the IR counterparts of GX17+2,

The Peculiar Infrared Counterpart of GX 17+2

We discuss the nature of the infrared (IR) counterpart of GX 17+2, one of the most luminous of the persistently bright X-ray binaries. Chandra HRC-S astrometry is consistent with either NP Ser (the

RXTE Observations of the Neutron Star Low-Mass X-Ray Binary GX 17+2: Correlated X-Ray Spectral and Timing Behavior

We have analyzed ~600 ks of Rossi X-Ray Timing Explorer data of the neutron star low-mass X-ray binary and Z source GX 17+2. A study was performed of the properties of the noise components and

Infrared Candidates for the Intense Galactic X-Ray Source GX 17+2

We present new astrometric solutions and infrared Hubble Space Telescope observations of GX 17+2 (X1813-140), one of the brightest X-ray sources on the celestial sphere. Despite 30 years of intensive

A connection between the X-ray spectral branches and the radio brightness in GX17 + 2

GX17 + 2 (4U 1813 – 14) is a bright X-ray binary1,2 in which matter is accreting on to a neutron star from a nearby companion. X-ray bursts, which are due to thermonuclear flashes on the surface of

X-Ray Spectra of Z Sources

A physically consistent model has been proposed that seeks to explain in a unified way the X-ray spectra and rapid variability of the Z sources and other weakly magnetic neutron stars in low-mass

A search for optical counterparts of nine galactic x-ray sources

Results of a photographic and spectrophotometric search to Bapprox.18.5 for the optical counterparts of nine galactic X-ray sources with good positions are reported. The sources included in this

Evidence for a jet contribution to the optical/infrared light of neutron star X-ray binaries

Optical/near-infrared (optical/NIR, OIR) light from low-mass neutron star X-ray binaries (NSXBs) in outburst is traditionally thought to be thermal emission from the accretion disc. Here we present a
