论文摘要
我们为Horava重力中的等温球构建玩具模型,如果选择了参数,则包括爱因斯坦的重力。等温球的方程是从引力粒子系统的分区函数得出的。我们确认该系统的牛顿极限与众所周知的等温球的模型一致。发现等温球的稳定性对球体中心的能量密度敏感。
We construct a toy model for isothermal spheres in Horava gravity, which includes Einstein's gravity if a parameter is appropriately chosen. The equations for the isothermal spheres are derived from the partition function of the gravitating particle system. We confirm that the Newtonian limit of the system coincides with the model of the well-known isothermal sphere. The stability of the isothermal sphere is found to be sensitive to the energy density at the center of the sphere.
