摘要

最近的 Chandra 观测提高了对 RX J185635-3754 和 3C58 这两类天体的期望,这些天体要么是裸露的奇异 quark 星,要么是拥有扩张 quark 核心的星体。然而,这些观测也可被解释为常规中子星。要么是前者,要后者的解释,都必须同时满足以下三个观测要求:(i) 光谱特征(即热辐射或非热辐射,可能存在线状特征)、(ii) 对推定质量 (M) 和半径 (R) 的限制,以及 (iii) 随年龄变化的冷却曲线(有效温度 T 与亮度 L)。中子星紧凑体 offers the promise of in a fashion complementary to relativistic heavy ion collider experiments, which largely address the finite temperature, but baryon poor regime. This paper provides a review of the variants of dark matter (CDM, HDM) which are thought to be fundamental components of the universe and their role in origin and evolution of structures.
