摘要:

软伽马射线中继器SGR 1806-20一直吸引着大量的关注,因为它在2004年12月发出了有史以来观测到的最强大的巨型耀斑。在这里,我们介绍了SGR 1806-20的第一个朱雀观测结果,它似乎已经达到了一个以接近耀斑前水平的通量和相对较软的光谱为特征的状态。尽管如此,源仍然相当活跃,朱雀观测到的几次短暂爆发证明了这一点。我们讨论了宽带光谱特性的SGR 1806-20的背景下的磁星模型,考虑其最近的理论发展。

英文摘要:

The soft gamma-ray repeater SGR 1806-20 has been attracting a lot of attention owing to the fact that in December 2004 it emitted the most powerful giant flare ever observed. Here we present the results of the first Suzaku observation of SGR 1806-20, that seems to have reached a state characterized by a flux close to the pre-flare level and by a relatively soft spectrum. Despite this, the source remained quite active, as testified by several short bursts observed by Suzaku. We discuss the broadband spectral properties of SGR 1806-20 in the context of the magnetar model, considering its recent theoretical developments.
