EoS和旋转中子星的核约束

Nuclear constraints on the EoS and rotating neutron stars

A. E. L. Dieperink, C. Korpa

摘要:

本文讨论了核约束对中子星状态方程的影响。一个综合的适合核质量和电荷半径导致改进值的对称能及其衍生物在核饱和密度,$S_{\rm{v}}= 31$ MeV和$L=68\pm 8$ MeV。作为应用,讨论了旋转超大质量中子星的某些性质对EoS的敏感性。

英文摘要:

In this contribution nuclear constraints on the equation of state for a neutron star are discussed. A combined fit to nuclear masses and charge radii leads to improved values for the symmetry energy and its derivative at nuclear saturation density, $S_{\rm{v}}= 31$ MeV and $L=68\pm 8$ MeV. As an application the sensitivity of some properties of rotating supramassive neutron stars on the EoS is discussed.
