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).

在 de Sitter Space 中旋转黑色二进制文件


我们在广义相对论中用正宇宙学常数数值构造静止的、旋转的黑色双星。我们认为相同的黑洞具有对齐或反对齐的自旋。这两种情况的熵都比相应的单个 Kerr-Schwarzschild-de Sitter 黑洞小，具有相同的总角动量和宇宙视界熵。我们的解决方案在没有物质的广义相对论中建立了连续的非唯一性。它们还为自旋二进制合并问题（当添加轨道角动量时）提供初始数据。
