摘要：
通过引入Weyl张量与应力能张量之间的耦合，修改Einstein-Hilbert拉格朗日量以解释无暗物质的银河旋转曲线。该耦合常数通过拟合银河系和M31的旋转速度确定，采用变量密度模型分析七个边缘螺旋星系及银河系。
英文摘要：
A modification of the Einstein-Hilbert Lagrangian by introducing a coupling between the Weyl tensor and the stress-energy tensor was proposed to explain flat galactic rotation curves without the exotic (non-baryonic) dark matter (DM) [1]. The proposed coupling constant was previously determined by fitting the rotational velocities of the Milky Way and M31 modeled with constant density, yielding the same coupling constant for both [2,3]. In this work, we have modified the formalism for a variable density by modeling the galactic systems with realistic, spherically symmetric and radially varying density profiles for the baryonic matter and this analysis is applied to seven edge-on spiral galaxies of the local cluster [4-10] and the Milky Way.
