Evolving Neutron Star Low-Mass X-ray Binaries to Ulta-compact X-ray Binaries

TL;DR

This paper explores the evolutionary pathways of neutron star low-mass X-ray binaries (NS LMXBs) into ultra-compact X-ray binaries (UCXBs), proposing a new formation scenario involving circumbinary disks.

Contribution

It introduces a novel formation scenario for UCXBs from L/IMXBs utilizing circumbinary disks, expanding understanding of their evolutionary processes.

Findings

Proposed a scenario for UCXB formation involving CB disks.

Presented evolutionary results of NS LMXBs leading to UCXBs.

Discussed implications for the formation of ultra-compact systems.

Abstract

The author presented the results on the evolution of NS LMXBs and the formation of UCXBs(Ma & Li 2009 for details), and proposed a scenario for the formation of UCXBs from L/IMXBs with the aid of a CB disk in this work.
