Halo dark matter, if it is baryonic, may plausibly consist of compact stellar remnants. Jeans mass clouds containing 10(6) to 10(8) solar masses could have efficiently formed stars in the early universe and could plausibly have generated, for a suitably top-heavy stellar initial mass function, a high abundance of neutron stars as well as a small admixture of long-lived low mass stars. Within the resulting clusters of dark remnants, which eventually are tidally disrupted when halos eventually form, captures of neutron stars by non-degenerate stars resulted in formation of close binaries. These evolve to produce, by the present epoch, an observable x-ray signal associated with dark matter aggregations in galaxy halos and galaxy cluster cores.
晕暗物质如果是重子物质，可能合理地由致密的恒星残骸组成。包含10⁶到10⁸个太阳质量的金斯质量云在早期宇宙中可能有效地形成恒星，并且对于适当的顶部较重的恒星初始质量函数，可能合理地产生大量的中子星以及少量长寿的低质量恒星。在由此产生的暗残骸星团中，当晕最终形成时，这些星团最终会受到潮汐破坏，非简并恒星对中子星的捕获导致形成密近双星。到当前时代，这些双星演化产生与星系晕和星系团核心中的暗物质聚集相关的可观测X射线信号。
