我们利用500米口径球面射电望远镜(FAST)发现了15个球状星团(GC)中的24颗脉冲星。其中包括在M2、M10和M14中发现的第一颗脉冲星。大多数新系统要么是确认的,要么可能是双星系统的成员。M53C和NGC 6517H和I是仅有的三颗被确认分离的脉冲星。M14A是一颗黑色寡妇脉冲星,轨道周期为5.5hr,最小伴星质量为0.016 M⊙。M14E是一颗食双星脉冲星,轨道周期为20.3小时。连同其他地方报道的其他8颗脉冲星,到目前为止,FAST总共发现了32颗GC脉冲星。此外,我们还检测到两次M3A。这足以确定它是一颗黑寡妇脉冲星,轨道周期为3.3hr,最小伴星质量为0.0125 M⊙。
We present the discovery of 24 pulsars in 15 globular clusters (GCs) using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). These include the first pulsar discoveries in M2, M10, and M14. Most of the new systems are either confirmed or likely members of binary systems. M53C and NGC 6517H and I are the only three pulsars confirmed to be isolated. M14A is a black widow pulsar with an orbital period of 5.5 hr and a minimum companion mass of 0.016 M ⊙. M14E is an eclipsing binary pulsar with an orbital period of 20.3 hr. With the other 8 discoveries that have been reported elsewhere, in total 32 GC pulsars have been discovered by FAST so far. In addition, We detected M3A twice. This was enough to determine that it is a black widow pulsar with an orbital period of 3.3 hr and a minimum companion mass of 0.0125 M ⊙.
