Chandra follow - up of bursters with low persistent emission
نویسندگان
چکیده
We report on Chandra ACIS-S observations of five type I X-ray bursters with low persistent emission: We designate candidate persistent sources for four X-ray bursters. All candidates are detected at a persistent luminosity level of 10 32−33 erg s −1 , comparable to soft X-ray transients in quiescence. From the number of bursters with low persistent emission detected so far with the Wide Field Cameras, we estimate a total of such sources in our Galaxy between 30 and 4000.

We carried out Chandra observations of two low-luminosity low-mass X-ray binaries, 1RXS J170854.4– 321857 and 1RXS J171824.2–402934, for which previously single X-ray bursts had been detected with the Wide Field Cameras (WFCs) on board BeppoSAX. Both were detected in our Chandra observations in an actively accreting state three to eight years after the X-ray bursts, with 0.5–10 keV luminosities...

متن کاملSpectral Properties of a Sample of Low Luminosity Type I X-ray Bursters
I report on a sample of new type I X-ray bursters, firstly detected with the Wide Field Cameras on board BeppoSAX and then studied with the Narrow Field Instruments on a broad spectral range (0.1-200 keV). Properties of the transient/persistent emission are summarized and the broad band X-ray spectra discussed in detail for a few sources.

Background: Standard treatment of Gestational Trophoblastic Disease (GTD) is chemotherapy. Single-agent chemotherapy regime including Methotrexate (MTX) or Actinomycin. Single-agent is widely used in treatment of persistent trophoblastic disease. We reported an uncommon toxicity of low-dose single-agent methotrexate in a patient. Case Presentation: A 20-year-old woman, primary gravid after two ...
متن کاملBeppoSAX Wide Field Cameras observations of six type I X-ray bursters
We have discovered three certain (SAXJ1324.5−6313, 2S 1711−339 and SAXJ1828.5−1037) and two likely (SAXJ1818.7+1424 and SAXJ2224.9+5421) new thermonuclear X-ray burst sources with the BeppoSAX Wide Field Cameras, and observed a second burst ever from a sixth one (2S 0918−549). Four of them (excluding 2S 1711−339 and 2S 0918−549) are newly detected X-ray sources from which we observed single bur...
