论文摘要
暗物质(DM)可以在散射后的天体中捕获并失去足够的能量以在重力上绑定。我们得出了一个描述天体内部物体中当前DM分布的一般框架,该框架自言自语包括浓度扩散,热扩散,重力和捕获积累的影响。对于具有足够相互作用的DM,我们表明大量的DM种群可以热化并坐在天体表面。这种浮动分布允许在广泛的天体中进行DM搜索的新现象学,包括太阳,地球,木星,棕色矮人和系外行星。
Dark matter (DM) can be captured in celestial bodies after scattering and losing sufficient energy to become gravitationally bound. We derive a general framework that describes the current DM distribution inside celestial objects, which self-consistently includes the effects of concentration diffusion, thermal diffusion, gravity, and capture accumulation. For DM with sufficient interactions, we show that a significant DM population can thermalize and sit towards the celestial-body surface. This floating distribution allows for new phenomenology for DM searches in a wide range of celestial bodies, including the Sun, Earth, Jupiter, Brown Dwarfs, and Exoplanets.
