论文摘要
我们介绍了欧洲X射线监视器（JEM-X）和IBIS/ISGRI仪器在整体卫星上观察到的长时间持续时间爆发目录。 14次爆发的电子折叠时间范围从55 s到？ 17分钟，因此被归类为由异常厚的氦层的点火引起的中间持续爆发。尽管文献中已经报道了七个事件，但我们已经系统地重新分析了整个样本。我们发现文献中未报告的三个新的光球半径扩展（PRE）爆发，这使我们能够对这些来源的距离进行新的估计。我们将增强的持续发射方法（也称为FA方法）应用于爆发前可检测到的持续发射的来源，以遵循爆发期间积聚率的演变。尽管我们没有明显的拟合，但FA因子的演变显示出一种指示性行为，我们将讨论这一点。
We present a catalog of long duration bursts observed with the Joint European X-ray Monitor (JEM-X) and IBIS/ISGRI instruments onboard the INTEGRAL satellite. The fourteen bursts have e-folding times ranging from 55 s to ? 17 min, and are therefore classified as intermediate-duration bursts, caused by the ignition of an unusually thick helium layer. Though seven events have already been reported in literature, we have systematically re-analyzed the whole sample. We find three new photospheric radius expansion (PRE) bursts, which are not reported in the literature, allowing us to provide a new estimate of the distances to these sources. We apply the enhanced persistent emission method (also known as the fa method) on sources with detectable persistent emission prior to a burst, in order to follow the evolution of the accretion rate during the burst. Although we do not get significantly better fits, the evolution of the fa factor shows an indicative behavior, which we discuss.
