X-Ray Eclipse Timing in the LMXB EXO0748-676

چکیده
Orbital period changes are an important diagnostic for understanding low mass X-ray binary (LMXB) accretioninduced angular momentum exchange and overall system evolution. We present our most recent results for the eclipse timing of the LMXB EXO 0748−676. Since its discovery in 1985 it has apparently undergone three distinct orbital period “epochs", each characterized by a different orbital period than the previous epoch. We outline the orbital period behavior for EXO 0748−676 over the past 18 years and discuss the implications of this behavior in light of current theoretical ideas for LMXB evolution.

We report our complete database of X-ray eclipse timings of the low mass Xray binary EXO0748−676 observed by the Rossi X-Ray Timing Explorer (RXTE) satellite. As of this writing we have accumulated 443 full X-ray eclipses, 392 of which have been observed with the Proportional Counter Array on RXTE. These include both observations where an eclipse was specifically targeted and those eclipses fou...
متن کاملEclipse Timings of the Low Mass X-ray Binary EXO 0748–676 III. An Apparent Orbital Period Glitch Observed with USA and RXTE
We present 7 eclipse timings of the low mass X-ray binary EXO0748−676 obtained with the USA experiment during 1999−2000 as well as 122 eclipse timings obtained with RXTE during 1996−2000. According to our analysis, the mean orbital period has increased by ∼ 8 ms between the pre-RXTE era (1985−1990) and the RXTE/USA era (1996−2000). This corresponds to an orbital period derivative of Porb/Ṗorb ∼...
متن کاملDiscovery of long - term superorbital periodicities in the pseudo - transient
Long-term monitoring of the recently discovered X-ray transient, IGR J17098-3628, by the All Sky Monitor on board the Rossi X-ray Timing Explorer, has shown that it displays a long term (≈ 163d) quasi-periodic modulation in the data spanning its " active " state (i.e. approximately MJD 53450-54200). Furthermore, this light-curve is not typical of " classical " soft X-ray transients, in that J17...
متن کاملThe broad-band X–ray spectrum of the dipping Low Mass X-ray Binary EXO0748–676
We present results of a 0.1-100 keV BeppoSAX observation of the dipping low-mass X-ray binary (LMXRB) EXO0748–676 performed in 2000 November. During the observation EXO0748–676 exhibited X-ray eclipses, type I X-ray bursts and dipping activity over a wide range of orbital phases. The 0.1–100 keV “dip– free”(ie. dipping and eclipsing intervals excluded) spectrum is complex, especially at low-ene...
متن کاملA Strong X-ray Burst from the Low-mass X-ray Binary Exo 0748 676
We have observed an unusually strong X-ray burst as a part of our regular eclipse timing observations of the lowmass binary system EXO 0748 676. The burst peak flux was 5:2 ; 10 8 ergs cm s , approximately 5 times the normal peak X-ray burst flux observed from this source by RXTE. Spectral fits to the data strongly suggest that photospheric radius expansion occurred during the burst. In this pa...
