We demonstrate that black holes and stars in general relativity can be destabilized by perturbations of nonminimally coupled vector fields. Focusing on static and spherically symmetric backgrounds, our analysis shows that black holes with sufficiently small mass and stars with sufficiently high densities are subject to ghost- or gradient-type instabilities. This holds for a large class of Einstein-Proca theories with nonminimal couplings, including generalized Proca models that have sparked attention for their potential role in cosmology and astrophysics. The stability criteria translate into bounds of relevance for low-scale theories of dark energy and for ultralight dark matter scenarios.

广义普罗卡场对黑洞和恒星的破坏

我们证明了广义相对论中的黑洞和恒星可能会因非最小耦合矢量场的扰动而不稳定。专注于静态和球对称背景，我们的分析表明，质量足够小的黑洞和密度足够高的恒星会受到鬼影或梯度型不稳定性的影响。这适用于一大类具有非最小耦合的爱因斯坦-普罗卡理论，包括因其在宇宙学和天体物理学中的潜在作用而引起关注的广义普罗卡模型。稳定性标准转化为低尺度暗能量理论和超轻暗物质场景的相关界限。
