论文摘要
我们已经发现并分析了中子巨星低质量X射线二进制二进制4U 1636 $ -53的16次多峰型I爆发，其中Rossi X射线计时探索器（RXTE）。其中之一是罕见的四峰爆发，以前没有报道。所有16次爆发都不仅在X射线光曲线中，而且在侧侧光曲线中均显示了多声明的结构。在颜色彩色图中从硬状态到软状态的过渡期间，大多数多峰爆发都出现在观察结果中。我们发现第二峰通量与两个峰之间的分离时间之间存在抗相关性。我们还发现，在双峰爆发中，峰值比率和前爆发光谱中的热成分的温度相关。这表明爆发的光曲线中的双峰结构可能会受到盘中增强的增生率或中子恒星温度升高的影响。
We have found and analysed 16 multi-peaked type-I bursts from the neutron-star low mass X-ray binary 4U 1636$-$53 with the Rossi X-ray Timing Explorer (RXTE). One of the bursts is a rare quadruple-peaked burst which was not previously reported. All 16 bursts show a multi-peaked structure not only in the X-ray light curves but also in the bolometric light curves. Most of the multi-peaked bursts appear in observations during the transition from the hard to the soft state in the colour-colour diagram. We find an anti-correlation between the second peak flux and the separation time between two peaks. We also find that in the double-peaked bursts the peak-flux ratio and the temperature of the thermal component in the pre-burst spectra are correlated. This indicates that the double-peaked structure in the light curve of the bursts may be affected by enhanced accretion rate in the disc, or increased temperature of the neutron star.
