论文摘要
银河中心区域中某些X射线源的存在，这些X射线源显示出可变性，但在十多年的监测中没有显示出爆发的爆发，以争取在该地区存在大量恒星质量黑洞。这些对象正在积聚黑洞的论点的核心要素是，低质量X射线二进制（LMXB）中的中子星（NSS）没有长时间的短暂复发时间。我们在本文中证明，大约一半的已知瞬态LMXB具有明确的NS原始签名，其复发时间超过了十年来爆发，以爆发。我们还表明，为了使NS LMXB的预期总人数与观察到的一个人，以及与毫秒的无线电脉冲星人（MSRP）人群，复发时间超过一个世纪以上的爆发可被Maxi等工具所检测到的爆发，必须是NS LMXBS的主导人群，并且已经发现了这些系统的占主导地位。
The presence of some X-ray sources in the Galactic Centre region which show variability, but do not show outbursts in over a decade of monitoring has been used to argue for the presence of a large population of stellar mass black holes in this region. A core element of the arguments that these objects are accreting black holes is the claim that neutron stars (NSs) in low mass X-ray binaries (LMXBs) do not have long transient recurrence times. We demonstrate in this paper that about half of the known transient LMXBs with clear signatures for NS primaries have recurrence times in excess of a decade for outbursts at the sensitivity of MAXI. We furthermore show that, in order to reconcile the expected total population of NS LMXBs with the observed one and with the millisecond radio pulsar (MSRP) population of the Galaxy, systems with recurrence times well in excess of a century for outbursts detectable by instruments like MAXI must be the dominant population of NS LMXBs, and that few of these systems have yet been discovered.
