暗物質在中子星內的玻色-愛因斯坦凝聚

中子星具有強大的重力和較高的重子密度，是捕獲星際中的暗物質的理想場所。我們研究了由中子星捕獲並與核心熱化的自相互作用暗物質的影響。通過調整暗物質的質量、數量密度、暗物質-核子交互作用截面和暗物質-暗物質交互作用截面等參數，我們研究了捕獲的暗物質粒子達到了在中子星核心塌縮成黑洞的條件。特別是對於暗物質是玻色子的情況，玻色-愛因斯坦凝聚可能在積累的過程中發揮作用。我們用暗物質模擬了中子星的冷卻過程和熱化條件，並根據熱化和玻色-愛因斯坦凝聚之間的相互作用討論捕獲暗物質的數量演化。

Neutron star (NS) is an ideal place to capture the interstellar dark matter (DM) due to its strong gravity and high baryonic density. We study the effects of self-interacting DM which is captured by NS and thermalized with the core. By adjusting the parameters of DM such as mass, number density, DM-nucleon cross-section and DM-DM cross-section, we investigate the possibility of the captured DM particles to reach the collapse condition of black hole (BH) in NS core. In particular, for the case of DM is a bosonic particle, the Bose-Einstein Condensate (BEC) might play a role during accumulation. We simulate the cooling processes of NS and the thermalization condition with DM. We discuss the number evolution of DM according to the interplay between thermalization and BEC.
