标题： BeppoSAX and ASCA observations of the Galactic Bulge source 1E1743.1-2843

摘要： 我们报告了对位于银河系中心区域的X射线源1E1743.1-2843的BeppoSAX和ASCA观测结果，这些观测是在1993年至1998年之间进行的。 跨度近二十年的观测表明，1E1743.1-2843是一个持续的X射线源，很可能由致密星体吸积供能。 缺乏周期性脉冲以及相对较软的X射线谱支持这是一个包含中子星的低质量X射线双星系统的可能性。 然而，在超过650千秒的观测中未观察到I型X射线爆发，这使得其他解释也成为可能。 显示英文摘要

摘要： We report the results of BeppoSAX and ASCA observations of the X-ray source 1E1743.1-2843, located in the region of the galactic center, performed between 1993 and 1998. Observations spanning almost twenty years show that 1E1743.1-2843 is a persistent X-ray source, most likely powered by accretion onto a compact galactic object. The absence of periodic pulsations and the relatively soft X-ray spectrum favour a Low Mass X-ray Binary containing a neutron star. However, no Type I X-ray bursts have been observed in more than 650 ks of observations, leaving other interpretations possible.
