论文摘要
我们建议，最近发现的脉冲星是18.18分钟，GLEAM-X J162759.5-523504.3，很可能是一个热的subdwarf（Proto White Dwarf）。一个磁性偶极模型解释了高度磁化（$ \ sim 10^8 $ g）的观察到的周期和周期衍生，这是典型质量$ \ sim 0.5m_ \ odot $和半径$ \ sim 0.3r_ \ odot $的热点，以及$ \ sim 3 \ sim 3 \ sim 3 \ sim 3 \ tims 10^4 $ yr。 SubDwarf的旋转接近其分手速度，其旋转光度接近其爱丁顿的限制，这可能是由于同伴的积聚而导致的。
We suggest that the recently discovered, enigmatic pulsar with a period of 18.18 minutes, GLEAM-X J162759.5-523504.3, is most likely a hot subdwarf (proto white dwarf). A magnetic dipole model explains the observed period and period-derivative for a highly magnetized ($\sim 10^8$G), hot subdwarf of typical mass $\sim 0.5M_\odot$ and radius $\sim 0.3R_\odot$, and an age of $\sim 3\times 10^4$yr. The subdwarf spin is close to its breakup speed and its spindown luminosity is near its Eddington limit, likely as a result of accretion from a companion.
