论文摘要
对超新星残留物J1731-347中的中央紧凑型物体的分析表明，它的半径很小，更有趣的是，质量或小于一个太阳能质量。这就提出了一个天体物理过程可能导致如此小质量的问题，因为对各种SN爆炸的分析表明，不可能产生小于$ 1.17 m_ \ odot $的质量的中子星。在这里，我们表明，在奇怪的夸克恒星的情况下，可以获得订单的质量或小于一个太阳能，并且可以构建一个连贯的模型，不仅解释了该物体的质量和半径，而且在各种分析中也建议其缓慢的冷却。我们还表明，存在一条天体物理道路，导致这种物体的形成，我们讨论了假定构成暗物质的陌生人在这种情况下所扮演的角色。
The analysis of the central compact object within the supernova remnant HESS J1731-347 suggests that it has a small radius and, even more interestingly, a mass of the order or smaller than one solar mass. This raises the question of which astrophysical process could lead to such a small mass, since the analysis of various types of SN explosions indicate that is it not possible to produce a neutron star with a mass smaller than about $1.17 M_\odot$. Here we show that masses of the order or smaller than one solar mass can be obtained in the case of strange quark stars and that it is possible to build a coherent model explaining not only the mass and the radius of that object, but also its slow cooling suggested in various analyses. We also show that an astrophysical path exists which leads to the formation of such an object, and we discuss the role played in that scenario by strangelets assumed to constitute the dark matter.
