Simultaneous radio and X-ray observations of the low-mass X-ray binary GX 13+1
We present the results of two simultaneous X-ray/radio observations of the low-mass X-ray binary GX 13+1, performed in July/ August 1999 with the Rossi X-ray Timing Explorer and the Very Large Array. In X-rays the source was observed in two distinct spectral states; a soft state, which had a corresponding 6 cm flux density of ∼0.25 mJy, and a hard state, which was much brighter at 1.3–7.2 mJy. ...
متن کاملLow Mass X-ray Binary as the Progenitor of PSR J1713+0747
We have calculated the evolution of low-mass X-ray binaries that leads to the formation of the binary radio pulsars like PSR J1713+0747. We show that the mass transfer is most likely to be nonconservative, due to unstable disk accretion, to account for the mass of PSR J1713+0747, which is close to its initial value. We assume that part of the lost material from the binary may form a circumbinar...
متن کاملX-rays from quiescent low-mass X-ray binary transients
I argue that it is very unlikely that X-rays from quiescent black-hole low-mass X-ray binary transients are emitted by coronae of companion stars. I show that in a simple model in which these X-rays are emitted by an ADAF filling the inner part of an unsteady, dwarf-nova type disc, the X-ray luminosity is correlated with the orbital period. I predict what values of X-ray luminosities from black...
متن کاملLetter to the Editor X-ray observations during a Her X-1 anomalous low-state
Results of a 1999 July 8–10 BeppoSAX observation during an anomalous low-state of Her X-1 are presented. The standard on-state power-law and blackbody continuum model is excluded at high confidence unless partial covering is included. This gives a power-law photon index of 0.63±0.02 and implies that 0.28 ± 0.03 of the flux undergoes additional absorption of (27±7)×1022 atom cm−2. 11% of the obs...
متن کاملRxte 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 quasi-periodic oscillations (QPOs) as a function of the spectral properties, with the main goal to study the relation between the frequencies of the horizontal branch and upper kHz QPOs. It was found that...
