Anticorrelated Hard/Soft X-ray Emission from the X-Ray Burster 4U 0614+091
We have detected transient X-ray activity from the X-ray burster 4U 0614+091 simultaneously with BATSE/CGRO (20–100 keV) and ASM/RXTE (1–12 keV). The peak fluxes reach approximately 40 mCrab in both instruments over a period of about 20 days. The variable emission shows a clear anticorrelation of the hard X-ray flux with the soft X-ray count rate. The observed anticorrelation is another clear c...
متن کاملDiscovery of the Spin Frequency of 4U 0614+09 with Swift/BAT
We report the discovery of burst oscillations at 414.7 Hz during a thermonuclear X-ray burst from the low mass X-ray binary (LMXB) 4U 0614+091 with the Burst Alert Telescope (BAT) onboard Swift. In a search of the BAT archive, we found two burst triggers consistent with the position of 4U 0614+091. We searched both bursts for high frequency timing signatures, and found a significant detection a...
متن کاملSpitzer Reveals Infrared Optically - Thin Synchrotron Emission from the Compact Jet of the Neutron Star X - Ray Binary 4 U 0614 + 091
Spitzer observations of the neutron star (ultra-compact) X-ray binary (XRB) 4U 0614+091 with the Infrared Array Camera reveal emission of non-thermal origin in the range 3.5-8 µm. The mid-infrared spectrum is well fit by a power law with spectral index of α = −0.57 ± 0.04 (where the flux density is F ν ∝ ν α). Given the ultra-compact nature of the binary system, we exclude the possibility that ...

The disc - jet coupling in the neutron star X - ray binary
We study the accretion/ejection processes (i.e. disc/jet coupling) in the neutron star X-ray binary Aquila X-1 via a multi-wavelength approach. We use in the radio band the publicly available Very Large Array archive containing observations of the object between 1986–2005, in the X-ray band the archival Rossi X-ray Timing Explorer data (Proportional Counter Array and High Energy X-ray Timing Ex...
