Cir X-1的X射线/射电同步观测

Simultaneous X-ray/radio observations of Cir X-1

Paolo Soleri, Valeriu Tudose, Rob Fender, Michiel van der Klis

摘要:

我们分析了同时X射线/无线电观测的CircinusX-1分别收集与RXTE和ATCA在2000年10月和2002年12月,并确定无线电耀斑接近相位0.0和0.5的轨道周期。到目前为止,只有间接证据表明无线电耀斑接近0.5级。此外,在我们的数据集中,我们清楚地将射电耀斑和X射线光谱定时变化与相位0.0相关联。对于黑洞X射线双星,X射线和射电波段之间的关系已经很清楚了,而对于中子星X射线双星,仍然缺乏一个清晰完整的关系。

英文摘要:

We analysed simultaneous X-ray/radio observations of Circinus X-1 collected respectively with RXTE and ATCA in 2000 October and 2002 December and identified radio flares close to phase 0.0 and 0.5 of the orbital period. To date, there is only circumstantial evidence for radio flares near phase 0.5. Moreover, in our data set, we clearly associated both a radio flare and X-ray spectral timing changes with phase 0.0. While for black hole X-ray binaries the picture of the association between the X-ray and the radio bands is quite well understood, for neutron star X-ray binaries a clear and complete picture is still missing.
