摘要:

基于对X射线新星H 1743 -322(IGR J17464-3213)和GX 339 -4的长期SWIFT、RXTE和MAXI观测,我们研究了它们的X射线爆发的形态和光变曲线。特别是,我们已经证实了两个源中存在两种完全不同类型的爆发,软(S)和硬(H),并揭示了它们的变种,超亮(U)和中间(I)。根据截断吸积盘模型讨论了这些爆发光变曲线差异的性质和来源。

英文摘要:

Based on long-term SWIFT, RXTE, and MAXI observations of the X-ray novae H1743-322 (IGR J17464-3213) and GX339-4, we have investigated the morphology and classified the light curves of their X-ray outbursts. In particular, we have confirmed the existence of two radically different types of outbursts, soft (S) and hard (H), in both sources and revealed their varieties, ultrabright (U) and intermediate (I). The properties and origin of the differences in the light curves of these outbursts are discussed in terms of the truncated accretion disk model.
