中子星物质的对称能

Symmetry energy in neutron star matter

Claudio O. Dorso, Guillermo A. Frank, Jorge A. Lopez

摘要:

我们研究了质子中子比在x = 0.1~0.5之间、密度在0.02 fm-3~0.085 fm-3之间、温度T <4 MeV的中子星物质的结构。特别是,我们研究的面食形状和以前观察到的核物质的相变,以及对称性能量的行为。我们证实了均匀的非均匀相变的存在,以及在不同的密度和温度下的对称能的不同值。

英文摘要:

We investigate the structure attained by neutron star matter with proton to neutron ratios ranging from x=0.1 to 0.5, densities in the range of 0.02 fm-3 to 0.085 fm-3, and temperatures T<4 MeV. In particular we study the pasta shapes and the phase changes previously observed in nuclear matter, as well as the behavior of the symmetry energy. We corroborate the existence of homogeneous to non-homogeneous phase transitions, and the different values of the symmetry energy at different densities and temperatures.
