Inverse Chameleon Mechanism and Mass Limits for Compact Stars
Hao Wei, Zhong-Xi Yu
As is well known, there are various mass limits for compact stars. For example, the maximum mass for non-rotating white dwarfs is given by the famous Chandrasekhar limit about $1.4…
Neutron Star as a Mirror for Gravitational Waves
Hao Wei, Da-Chun Qiang, Zhong-Xi Yu +1
Gravitational wave (GW) has become one of the most active fields in physics and astronomy since the first direct detection of GW event in 2015. As is well known, multiple images of…
Lemaitre-Tolman-Bondi Static Universe in Rastall-like Gravity
Zhong-Xi Yu, Shou-Long Li, Hao Wei
In this work, we try to obtain a stable Lemaitre-Tolman-Bondi (LTB) static universe, which is spherically symmetric and radially inhomogeneous. However, this is not an easy task, a…
Catalyst type of interactions between dark energy and dark matter
Yan-Hong Guo, Zhong-Xi Yu, Ji-rong Ren
In this paper, we focus on three specific interactions of dark sector in the existence of baryonic matter and radiation. First, we attempt to assume baryonic matter and radiation c…
