摘要:

截至2022年11月,已在36个球状星团(GC)中发现了267颗双星。本文介绍了我们对GC脉冲星参数分布和探测效率的研究。在GC中,已知谱的色散测度的平均值($\overline{\rm DM}$)与色散测度差($Δ{\rm DM}$)之间的幂律关系为$\lgΔ{\rm DM} \propto 1.52 \lg \overline{\rm DM}$。灵敏度可能是找到更多间谍的关键。因此,在射电望远镜建成若干年后,GC脉冲星的数量将相应增加。我们认为,目前在南半球的GC可能有更高的可能性,以找到新的恒星。

英文摘要:

Up to November 2022, 267 pulsars have been discovered in 36 globular clusters (GCs). In this paper, we present our studies on the distribution of GC pulsar parameters and the detection efficiency. The power law relation between the average of dispersion measure ($\overline{\rm DM}$) and dispersion measure difference ($Δ{\rm DM}$) of known pulsars in GCs is $\lgΔ{\rm DM} \propto 1.52 \lg \overline{\rm DM}$. The sensitivity could be the key to find more pulsars. As a result, several years after the construction of a radio telescope, the GC pulsar number will be increased accordingly. We suggest that currently GCs in the southern hemisphere could have higher possibilities to find new pulsars.
