论文摘要
已经研究了二次重力的静态2-2孔溶液，它可能是黑洞的无水平替代品，作为重力塌陷的终点。实际上，这种物体将与自旋形成，但是目前尚不清楚旋转2-2孔溶液。我们在这里采取一些步骤来探索此类解决方案的存在和属性。我们采用了与对象大小成反比的字段方程的扩展。该扩展参数明确出现在试验指标中，我们能够找到领先的阶场方程的解决方案。这些真空溶液是描述旋转2-2孔的大部分内部的候选者。
Static 2-2-hole solutions of quadratic gravity have been investigated to be a possible horizonless replacement for black holes as the endpoint of gravitational collapse. Realistically such objects will form with spin, but rotating 2-2-hole solutions are currently not known. We take some steps here to explore the existence and properties of such solutions. We employ an expansion of the field equations where the expansion parameter is inversely related to the size of the object. This expansion parameter appears explicitly in the trial metrics, and we are able to find solutions of the leading order field equations. These vacuum solutions are candidates to describe most of the interior of a rotating 2-2-hole.
