中子星状态方程的因果表示

Causal Representations of Neutron-Star Equations of State

Lee Lindblom

摘要:

状态方程的参数化表示在利用天文观测测量中子星核内物质性质的努力中起着重要作用。这里提出了新的表示,能够表示任何状态方程的任何所需的精度水平,同时自动施加因果关系和热力学稳定性约束。数值试验,测量这些新的参数化表示的因果核理论模型状态方程的集合的准确性和有效性。

英文摘要:

Parameterized representations of the equation of state play an important role in efforts to measure the properties of the matter in the cores of neutron stars using astronomical observations. New representations are presented here that are capable of representing any equation of state to any desired level of accuracy, while automatically imposing causality and thermodynamic stability constraints. Numerical tests are presented that measure how accurately and efficiently these new parameterizations represent a collection of causal nuclear-theory model equations of state.
