孤立毫秒脉冲星(IMSPs)是学术争议的一个话题。有多种模型来解释它们的形成。我们探究通过夸克星爆发(QN)形成孤立毫秒脉冲星的过程。在这个形成过程中,低质量X射线双星(LMXBs)会被瓦解 。 注:原文“are disrupt”表述有误,应为“are disrupted” 。
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. Using population synthesis, this work estimates that the galactic birthrate of QN-produced IMSPs lies betweenand. 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.
