X射线暴和超暴--最近的发展

X-ray bursts and superbursts - recent developments

Jean in 't Zand

摘要:

在过去的15年里,X射线暴研究在观测和理论上都取得了许多有趣的新进展。新的现象被发现,如爆发振荡和超级爆发,并确定了热核燃烧的新机制。在未来几年里,利用现有和未来仪器进行研究的一个重要驱动力是对中子星基本参数的追求。然而,其他几个更直接的问题也迫切需要答案。例如,超级暴是如何被点燃的,为什么暴尾中存在暴振荡?我们简要回顾了最近的发展,并讨论了MAXI可以发挥的作用。得益于MAXI的大可见度窗口和大占空比,它特别适合研究罕见的长持续时间爆发(如超级爆发)的重现。简要介绍了MAXI数据的探索性研究。

英文摘要:

The past decade and a half has seen many interesting new developments in X-ray burst research, both observationally and theoretically. New phenomena were discovered, such as burst oscillations and superbursts, and new regimes of thermonuclear burning identified. An important driver of the research with present and future instrumentation in the coming years is the pursuit of fundamental neutron star parameters. However, several other more direct questions are also in dire need of an answer. For instance, how are superbursts ignited and why do burst oscillations exist in burst tails? We briefly review recent developments and discuss the role that MAXI can play. Thanks to MAXI's large visibility window and large duty cycle, it is particularly well suited to investigate the recurrence of rare long duration bursts such as superbursts. An exploratory study of MAXI data is briefly presented.
