摘要:

本文利用MJD 53724(爆发后)和MJD 55113之间的RXTE-PCA观测数据和MJD 54897上的Chandra-ACIS数据集(曝光量为20 ks),分析了Swift J1626.6+5156的脉冲轮廓。我们发现,脉冲轮廓显示形态的变化和脉动不停止,甚至$\sim 1200$天后爆发。尽管有这些变化,我们没有发现任何显着的变化,随着X射线通量的减少,脉冲分数。

英文摘要:

In this paper, we analyzed pulse profiles of Swift J1626.6+5156 using the lightcurves from RXTE-PCA observations between MJD 53724 (just after the outburst) and MJD 55113 and a Chandra-ACIS dataset on MJD 54897 with a 20 ks exposure. We found that pulse profiles show morphological variations and pulsations do not cease even $\sim 1200$ days after the outburst. Despite these variations, we did not find any significant variation in the pulsed fraction with decreasing X-ray flux.
