Isolated millisecond pulsars (IMSPs) are a topic of academic contention. There are various models to explain their formation. We explore the formation of IMSP via quark novae (QN). During this formation process, low-mass X-ray binaries (LMXBs) are disrupted when the mass of the neutron star (NS) reaches \(1.8M_\odot \). Using population synthesis, this work estimates that the galactic birthrate of QN-produced IMSPs lies between \({\sim }9.5\times 10^{-6}\) and \({\sim }1.7\times 10^{-4}\) \(\mathrm{yr}^{-1}\). The uncertainties shown in our experiment model is due to the QN’s kick velocity. Furthermore, our findings not only show that QN-produced IMSPs are statistically more significant than those produced by mergers, but also that millisecond pulsar binaries with a high eccentricity may originate from LMXBs that have been involved in, yet not disrupted by, a QN.

夸克新星：形成孤立毫秒脉冲星的替代通道

孤立的毫秒脉冲星 (IMSP) 是学术争论的话题。有各种模型来解释它们的形成。我们通过夸克新星 (QN) 探索 IMSP 的形成。在这个形成过程中，当中子星 (NS) 的质量达到 \(1.8M_\odot \) 时，低质量 X 射线双星 (LMXB) 被破坏。使用人口合成，这项工作估计 QN 产生的 IMSP 的银河出生率介于 \({\sim }9.5\times 10^{-6}\) 和 \({\sim }1.7\times 10^{-4 }\) \(\mathrm{yr}^{-1}\)。我们的实验模型中显示的不确定性是由于 QN 的反冲速度。此外，我们的研究结果不仅表明 QN 产生的 IMSP 在统计上比合并产生的更显着，而且具有高离心率的毫秒脉冲星双星可能起源于参与过的 LMXB，
