最大质量中子星的普适性质:探索超致密物质的新工具

Universal properties of maximum-mass neutron stars: a new tool to explore superdense matter

D. D. Ofengeim

摘要:

我已经用不同的重子状态方程证明了最大质量中子星的质量、半径、中心密度和压力之间存在紧密的相关性。这些相关性提供了一个可能的解释。这种相关性的简单的解析形式的建议,并与观测的限制中子星的最大质量和它们的半径。假设稳定的中子星的状态方程是重子的,这提供了一个有价值的工具来限制它们可能达到的最大压力和密度。

英文摘要:

I have demonstrated the existence of a tight correlation between the mass, radius, central density, and pressure of maximum-mass neutron stars modeled using diverse baryonic equations of state. A possible explanation for these correlations is provided. Simple analytic forms of such correlations are suggested and compared with observational constraints on the maximum mass of neutron stars and their radii. This gives a valuable tool to constrain maximum pressure and density that could be reached in stable neutron stars, assuming their equation of state is baryonic.
