Abstract

We numerically construct stationary, rotating black binaries in general relativity with a positive cosmological constant. We consider identical black holes with either aligned or anti-aligned spins. Both cases have less entropy than the corresponding single Kerr–Schwarzschild–de Sitter black hole with the same total angular momentum and cosmological horizon entropy. Our solutions establish continuous nonuniqueness in general relativity without matter. They also provide initial data for the spinning binary merger problem (when orbital angular momentum is added).
德西特空间中旋转的黑双星
我们用数值方法在广义相对论中构建了具有正宇宙学常数的静止旋转黑洞。我们考虑了自旋对齐或反对齐的相同黑洞。这两种情况的熵都小于具有相同总角动量和宇宙学视界熵的相应单个克尔-施瓦兹希尔德-德西特黑洞。我们的解建立了广义相对论中无物质的连续非唯一性。它们还为旋转双星合并问题(当轨道角动量加入时)提供了初始数据。
