论文摘要
我们介绍了热核超新星的模拟，并与费米尼冷暗物质的扩展成分混合在一起。我们考虑使用带有球形对称性的Deflagration模型使用Deflagration模型来考虑Chandrasekhar-Mass White Dwarf的爆炸。暗物质成分的大小与正常物质相当，因此该系统由两维的一维欧拉水动力学描述。在我们所有考虑的模型中，爆炸使所有暗物质被捕获为残留的紧凑型黑星。与没有暗物质混合物的普通爆炸相比，暗物质的存在延长了幻影阶段，以产生更多的热中性和类似的铁组元素。暗物质混合模型会产生变暗和宽阔的光曲线，这挑战了热核超新星作为宇宙距离测量中标准蜡烛的作用。我们的结果还表明了深色紧凑物体的形成路径，该物体通过近极质量的暗物质混合热核超新星模仿亚 - 摩尔质量黑洞作为深色重力来源。
We present simulations of thermonuclear supernovae admixed with an extended component of fermionic cold dark matter. We consider the explosion of a Chandrasekhar-mass white dwarf using the deflagration model with deflagration-detonation transition with spherical symmetry. The dark matter component is comparable in size with that of the normal matter, and so the system is described by two-fluid, one-dimensional Eulerian hydrodynamics. The explosion leaves all the dark matter trapped as a remnant compact dark star in all of our considered models. The presence of dark matter lengthens the deflagration phase to produce more thermo-neutrinos and similar amounts of iron-group elements compared to those of ordinary explosions with no dark matter admixture. The dark matter admixed models produce dimmer and broader light curves, which challenge the role of thermonuclear supernovae as standard candles in cosmic distance measurement. Our results also suggest a formation path of dark compact objects which mimic sub-solar-mass black holes as dark gravitational sources, through near-solar-mass dark matter admixed thermonuclear supernovae.
