在Brueckner理论框架下,我们对对称核物质、纯中子物质和β稳定核物质的剪切粘性和热导率进行了数值研究。在一致的二体和三体相互作用下,计算了介质中的反应截面和核子有效质量。研究覆盖了中子星应用中所需的较宽的重子密度范围。用β稳定核物质输运系数的结果对中子星非径向模的阻尼时标作了初步的预测。
We present a numerical study of shear viscosity and thermal conductivity of symmetric nuclear matter, pure neutron matter, and beta-stable nuclear matter, in the framework of the Brueckner theory. The calculation of in-medium cross sections and nucleon effective masses is performed with a consistent two- and three-body interaction. The investigation covers a wide baryon density range as needed in the applications to neutron stars. The results for the transport coefficients in beta-stable nuclear matter are used to make preliminary predictions on the damping time scales of nonradial modes in neutron stars.
