摘要

我们研究了Brans-Dicke标量张量理论中的变色龙筛选机制。我们保留了典型变色龙机制的基本前提，即磁场在高密度环境中是巨大的，但在像太阳系这样的低密度环境中基本上是自由的。我们发现了静态和球对称体的薄壳解，并证明了该模型对局部数据的适用性。

Thin-shell Solution of Chameleon Mechanism in Brans-Dicke Scalar-Tensor Model

We investigated the chameleon screening mechanism in Brans-Dicke scalar-tensor theory. We preserved the fundamental premise of the typical chameleon mechanism, which is that the field is huge in high-density environments but essentially free in low-density environments like the solar system. We discovered thin-shell solutions for a static and spherical symmetric body and demonstrated the model’s applicability to local data.
