摘要:

本文介绍了1994年以来BHC IGR J17091-3624爆发的主要特征。自2003年以来,该源已被INTEGRAL和Swift广泛观察。特别是,我们报告的结果上一个2011年爆发,显示了罕见的变化行为之前只在银河系BH GRS 1915+105,但在不同的水平的流量。为了解释这种特殊的行为,已经提出了几种假设。在这里,我们根据它们之间明显的矛盾来讨论它们。最后,根据现有的资料,我们试图给出一个整体的看法,这个神秘的来源,我们推测的二元系统的演化状态。

英文摘要:

We present here the main characteristics of the BHC IGR J17091-3624 outbursts occurred several times since 1994. Since 2003, the source has been extensively observed by INTEGRAL and Swift. In particular, we report results on the last 2011 outburst that showed a rare variability behaviour observed before only in the galactic BH GRS 1915+105 but at a different level of flux. Several hypotheses have been proposed in order to explain this particular behaviour. They are all discussed here, in the light of their apparent contradiction. Finally, based on all available informations, we attempt to give an overall view of this enigmatic source and we speculate on the evolutionary state of the binary system.
