论文摘要
耗散性暗物质（DM）扇形的存在可能会允许在结构形成期间或通过增生在其寿命中捕获明显的DM质量，从而使恒星行为很好地影响到主序列阶段。在这种情况下，我们将上限放在当今的主序列中的分数DM质量上。使用双线光谱二进制（SB2恒星），提取引力肿块并与发光质量对比，并使用修饰的质量亮度关系得出，这说明了DM的影响。来自$ 0.18 <m/m_ \ odot <31 $质量范围的486个二元星样品的高含量质量和亮度数据被划分为适当的质量域并进行了分析。 95％C.L.在$ 1 <m/m_ \ odot <2.4 $制度中，发现263颗恒星子集的上限为5％。
The presence of a dissipative dark matter (DM) sector may allow for the trapping of a significant DM mass inside stars, either during structure formation or by accretion over their lifetime, influencing stellar behavior well into the Main Sequence stage. Motivated by this scenario, we place an upper bound on the fractional DM mass within current-day Main Sequence stars. Using double-lined spectroscopic binaries (SB2 stars), gravitational masses are extracted and contrasted with luminous masses, derived using a modified mass-luminosity relation which accounts for the effect of DM. High-accuracy mass and luminosity data from a sample of 486 binary stars in the $0.18 < M/M_\odot < 31$ mass range are partitioned into appropriate mass domains and analyzed. A 95% C.L. upper limit of sub-5% is found for the subset of 263 stars in the $1 < M/M_\odot < 2.4$ regime.
