论文摘要
最新的中子恒星质量（PSR J1614-2230，PSR J0348 + 0432，MSP J0740 + 6620）的测量限制了下限$ \ sim 2M _ {\ odot} $在这种紧凑的恒星的最大质量中，这使得大量质量存在于大量的恒星中，从而使其成为可能。带有参数集的相对论平均值场理论（包括KAON凝结）用于描述$β$平衡中中子星的性质。通过仔细选择$σ$ -CUT $C_σ$的参数，我们能够产生一个最大的质量中子星，带有Kaon凝结的最大质量中子星，比200万美元_ {\ odot} $重，我们发现该模型中$ρ-ω$相互作用的参数$λ_ν$对$ k^condens具有重大影响。在使用$σ$ -CUT方案的情况下，$ k^{ - } $冷凝仅在关闭$ρ-ω$交互时才发生。
The recent measurement of the mass of neutron stars (PSR J1614 - 2230, PSR J0348 + 0432, MSP J0740 + 6620) restricts the lower limit $\sim 2M_{\odot}$ of the maximum mass of such compact stars, making it possible for dense matter to exist in massive stars. The relativistic mean field theory with parameter sets FSUGold including Kaon condensation is used to describe the properties of neutron stars in $β$ equilibrium. Through careful choice of the parameter of the $σ$-cut $c_σ$, we are able to produce a maximum mass neutron star with Kaon condensation heavier than $2M_{\odot}$, and we find that the parameter $Λ_ν$ of the $ρ-ω$ interaction term in this model has a significant effect on $K^{-}$ condensation. In the case of using $σ$-cut scheme, $K^{-}$ condensation occurs only when the $ρ-ω$ interaction $Λ_ν$ is switched off.
