Collective excitations in the neutron star inner crust

L. Di Gallo, M. Oertel, M. Urban

摘要:

利用超流流体力学方法研究了中子星内壳非均匀相的集体激发谱。我们的目标是描述整个波长范围,从长波长的限制,可以描述的宏观方法,这是至关重要的低能量部分的光谱,波长的顺序的尺寸的维格纳-塞茨细胞,对应的模式通常描述在微观计算。作为一个应用程序,我们将讨论这些集体模式的“千层面”相的比热与其他已知的贡献相比的贡献。

英文摘要:

We study the spectrum of collective excitations in the inhomogeneous phases in the neutron star inner crust within a superfluid hydrodynamics approach. Our aim is to describe the whole range of wavelengths, from the long-wavelength limit which can be described by macroscopic approaches and which is crucial for the low-energy part of the spectrum, to wavelengths of the order of the dimensions of the Wigner-Seitz cells, corresponding to the modes usually described in microscopic calculations. As an application, we will discuss the contribution of these collective modes to the specific heat of the "lasagna" phase in comparison with other known contributions.
