论文摘要
这项工作专门用于最近引入的爱因斯坦 - 加斯 - 邦网重力。该理论可以绕过Lovelock定理,并避免Ostogragradsky的不稳定性。该理论的综合部分是GB术语为极限$ d \至4 $中的重力动态产生了非平凡的贡献。我们的主要兴趣是探索一类静态和球形对称的紧凑物体,该物体是在颜色味道锁定的奇怪物质(CFL)阶段制成的,其中所有三种夸克风味都对称地参与了配对。因此,自然要在4 $ d $ egb重力中要求紧凑的物体,因为紧凑的恒星签名可能是将新模型与爱因斯坦重力进行比较的测试床。另一方面,这可能会使紧凑型恒星中的CFL相可能存在新的启示。鉴于最近观察结果声称存在稳定的紧凑型\ emph {Quark}星(混合中子星或奇怪的恒星),此功能可能是相关的。
This work is devoted on the recently introduced Einstein-Gauss-Bonnet gravity in four dimensions. The theory can bypass the Lovelock's theorem and avoids Ostrogradsky instability. The integrated part of this theory is the GB term gives rise to a non-trivial contribution to the gravitational dynamics in the limit $D \to 4$. Our main interest is to explore a class of static and spherically symmetric compact objects made of strange matter in the color flavor locked (CFL) phase, in which all three quark flavors participate to pairing symmetrically. It is therefore natural to ask for compact objects in 4$D$ EGB gravity since, compact stars signatures may be the test-bed to compare new models to the Einstein gravity; on the other hand, this could shed new light on the possible presence of CFL phase in compact stars. This feature may be relevant in view of recent observations claiming the existence of stable compact \emph{quark} stars (hybrid neutron stars or strange stars).
