论文摘要
我们考虑中子恒星核核中的热导率，剪切粘度和动量松弛率。我们研究了三体力的核相互作用和模型的选择如何影响在Brueckner-Hartree-Fock多体核理论中计算的这些运输系数。我们发现，在相对较大的密度下，结果的模型依赖性很大。此外，我们提供了分析近似值，可以将我们的结果纳入实际模拟中。
We consider the thermal conductivity, shear viscosity, and momentum relaxation rates in the nucleon cores of the neutron stars. We study how the choice of the nuclear interaction and the model for three-body forces may affect these transport coefficients calculated within the Brueckner-Hartree-Fock many-body nuclear theory. We find that at relatively large densities the model dependence of the results is substantial. In addition we provide the analytical approximations which allow to incorporate our results in practical simulations.
