Abstract

Three physically reasonable static Weyssenhoff fluid sphere models have been obtained by solving the relevant field equations of the Einstein–Cartan theory of gravitation, when Weyssenhoff fluid is the source of spin and gravitation. The spin of the gravitating matter influences the fields of these fluid sphere models. The gravitational field of two of the models is proved to be of Petrov type \(D\), while the interpretation of the gravitational field of the remaining model fails due to the influence of the spin component \(s_{0}\). One of the fluid sphere models is accelerating and rotating, while the other two are only rotating. Gravity in each of these models repels and prevents the collapse.

爱因斯坦-卡坦引力理论中的静态Weyssenhoff流体球模型

在Weyssenhoff流体为自旋源和引力源的情况下，通过求解Einstein-Cartan引力理论的相关场方程，得到了三个物理上合理的静态Weyssenhoff流体球模型。重力物质的自旋影响这些流体球体模型的场。其中两个模型的引力场被证明为Petrov型\(D\)，而另一个模型的引力场由于自旋分量的影响，解释失败\(s_{0}\)。其中一个流体球模型是加速和旋转的，而另外两个只是旋转的。这些模型中的重力都排斥并阻止了坍缩。

期刊介绍： Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoplesâ€™ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
