旋转超流中子星中的温度相关振荡模

Temperature-dependent oscillation modes in rotating superfluid neutron stars

Vasiliy A. Dommes, Elena M. Kantor, Mikhail E. Gusakov

摘要:

我们计算了慢转超流中子星中惯性振荡模的谱,首次考虑了有限温度和超流中子与质子夹带的影响。我们在牛顿极限下工作,并假设最小的核心组成(中子,质子和电子)。我们还开发了一个近似的方法,允许一个计算的超流r-模式解析。最后,我们推导并分析了超流NS物质中惯性模在短波长极限下的色散关系。

英文摘要:

We calculate the spectrum of inertial oscillation modes in a slowly rotating superfluid neutron star, including, for the first time, both the effects of finite temperatures and entrainment between superfluid neutrons and protons. We work in the Newtonian limit and assume minimal core composition (neutrons, protons and electrons). We also developed an approximate method that allows one to calculate the superfluid r-mode analytically. Finally, we derive and analyze dispersion relations for inertial modes in the superfluid NS matter in the short wavelength limit.
