Complexity factor for a static self-gravitating sphere in Rastall-Rainbow gravity
Zhou-Li Ye, Yu Wang, Rui-Xin Yang +1
We generalized Herrera's definition of complexity factor for static spherically symmetric fluid distributions to Rastall-Rainbow theory of gravity. For this purpose, an energy-depe…

Tidal Love numbers of a nonexotic compact object with a thin shell
Rui-Xin Yang, Fei Xie, Dao-Jun Liu
As a possible alternative to black holes, horizonless compact objects have significant implications for gravitational-wave physics. In this work, we utilize the standard linearized…

Tidal Deformability of Neutron Stars in Unimodular Gravity
Rui-Xin Yang, Fei Xie, Dao-Jun Liu
Unimodular gravity is a modified theory with respect to general relativity by an extra condition that the determinant of the metric is fixed. Especially, if the energy-momentum ten…
