【摘要】：人們所熟知的核子中被證實還存在著夸克。作為費米子,高密下的夸克可以像電子一樣配對產(chǎn)生色超導,中子星由致密的核物質(zhì)組成,有學者認為色超導在中子星中存在�；谝陨衔锢肀尘�,本論文主要討論兩個內(nèi)容：色超導相以及旋轉(zhuǎn)頻率對中子星質(zhì)量半徑關系的影響；一味色超導相變潛熱的分析和計算。 我們通過給定各種狀態(tài)方程來研究中子星質(zhì)量半徑關系。首先得到了不同色超導相下的狀態(tài)方程,接著給定能隙△后對狀態(tài)方程做了比較,采用TOV方程的微擾法,分析不同色超導相下以及星體旋轉(zhuǎn)快慢對質(zhì)量半徑關系的影響。然后考慮能隙對化學勢的依賴關系,對狀態(tài)方程和質(zhì)量半徑關系做了再次分析。我們發(fā)現(xiàn)：不同的狀態(tài)方程,給出有差別的中子星的質(zhì)量半徑關系,同時旋轉(zhuǎn)頻率越大,同種色超導相下均給出質(zhì)量更大。 論文第二個工作是研究四種一味色超導相：CSL, Polar, Planar, A-phase,分析它們在強磁場中發(fā)生一級相變的潛熱,基于參數(shù)法首先求出熵的表達式隨后給出了熵和潛熱的數(shù)值結(jié)果。潛熱勢必會影響到中子星的熱演化,這個影響將在后續(xù)工作進行討論。 最后對論文所研究的內(nèi)容進行小結(jié)和展望,附錄是對調(diào)研中子星時計算傳播子的總結(jié)。
[Abstract]:It was confirmed that the well-known nucleons are composed of quarks. As fermions, high density quarks like electrons can produce color superconducting pairing, the neutron star by dense nuclear matter, some scholars believe that exist in neutron stars. Based on the above background color superconducting physics, this paper focuses on two aspects: color the superconducting phase and the rotating frequency of the neutron star mass radius relation; analysis and calculation of a color superconductivity phase change latent heat.
We are given by the state equations of the neutron star mass radius relations. State equations are firstly obtained under different color superconducting phases, and then given the energy gap of delta state equation were compared, perturbation method using TOV equation, analysis of different color superconducting phases and the rotating speed of the star effect of mass radius relations then consider the chemical potential dependence of the gap, the equation of state and the mass radius relation was analysed again. We found that the equation of state and the mass radius relation of the neutron star will give different, the greater the rotation frequency, under each kind of color superconductivity gives greater quality.
The second work is a study of four kinds of color superconductivity phase: CSL, Polar, Planar, A-phase, analysis of their latent heat phase transition in a strong magnetic field, parameter method first computes the entropy expression then numerical results were proposed based on the entropy and latent heat. The latent heat is bound affect the thermal evolution of neutron stars the effect of this will be discussed in subsequent work.
Finally, the contents of the paper are summarized and prospected, and the appendix is a summary of the calculation propagator of the neutron star.
