摘要:

在本文中,我们给出了鲍文荧光调查的评论,显示窄的发射线(主要是NIII和CIII线之间的4630和4660 A)似乎普遍存在于光学明亮的低质量X射线双星鲍文混合。这些窄谱线归因于伴星的后处理,给出了K_2的第一个估计,从而提供了对它们的系统参数的第一个约束。我们将概述对致密天体质量的限制,并简要强调调查中最重要的结果。此外,我们将指出最有前途的系统,为未来的后续研究,并指出我们认为如何提高他们的组件质量的估计。

英文摘要:

In this paper we give a review of the Bowen fluorescence survey, showing that narrow emission lines (mainly NIII and CIII lines between 4630 and 4660 A) appear to be universally present in the Bowen blend of optically bright low mass X-ray binaries. These narrow lines are attributed to reprocessing in the companion star giving the first estimates of K_2, and thereby providing the first constraints on their system parameters. We will give an overview of the constraints on the masses of the compact objects and briefly highlight the most important results of the survey. Furthermore, we will point out the most promising systems for future follow-up studies and indicate how we think their estimates of the component masses can be improved.
