标题： Superfluid effects on gauging core temperatures of neutron stars in low-mass X-ray binaries

摘要： 中子星从低质量伴星吸积物质时，由于中子星表面物质的热核爆炸而被观测到发生X射线爆发。 我们利用关于超流和超导特性的最新结果，表明在这些中子星的观测吸积率范围内，核心温度可能无法唯一确定。 推断的核心温度的不确定性可能有助于解释具有多个爆发之间非常短复发时间的中子星与具有较长爆发之间复发时间的中子星之间的差异：短爆发源具有较高的温度和正常的中子星核心，而长爆发源具有较低的温度和超流中子。 如果正确的话，可以从短爆发源中最低亮度和长爆发源中最高亮度的测量值用来限制中子超流开始的临界温度。 显示英文摘要

摘要： Neutron stars accreting matter from low-mass binary companions are observed to undergo bursts of X-rays due to the thermonuclear explosion of material on the neutron star surface. We use recent results on superfluid and superconducting properties to show that the core temperature in these neutron stars may not be uniquely determined for a range of observed accretion rates. The degeneracy in inferred core temperatures could contribute to explaining the difference between neutron stars which have very short recurrence times between multiple bursts and those which have long recurrence times between bursts: short bursting sources have higher temperatures and normal neutrons in the stellar core, while long bursting sources have lower temperatures and superfluid neutrons. If correct, measurements of the lowest luminosity from among the short bursting sources and highest luminosity from among the long bursting sources can be used to constrain the critical temperature for the onset of neutron superfluidity.
