Monsters and neutron stars
AI总结：
本研究提出质量数A>10^7的接近最大同位旋的亚稳态原子核（巨核），其寿命在A>10^39时超100皮秒，或产生于双中子星并合，可在近期引力波实验中探测。
AI中文摘要：
利用量纲分析和其他简单估算，研究指出质量数A>10^7的原子核分支若具有接近最大同位旋则可能是亚稳态的，该分支与中子星是连续的。这些假设的亚稳态原子核（我们称之为“巨核”）最快的衰变模式是通过中子蒸发。我们对其寿命进行估算，表明当A>10^39时，寿命可能超过100皮秒。我们推测它们在双中子星并合中产生，在此过程中，其寿命可能进一步延长，且它们的存在可在近期的引力波实验中被探测到。
英文摘要：
Using dimensional arguments and other simple estimates, it is pointed out that a branch of nuclei with mass number A>10^7 could be metastable if they have close to maximal isospin. This branch is continuous with neutron stars. The fastest decay mode of these hypothetical metastable nuclei (which we call monsters) is through neutron evaporation. We present an estimate of the lifetime and show it could be more than 100 ps for A>10^{39}. We speculate about their creation in binary neutron star mergers, where we argue that their lifetimes could be extended further, and their presence could be detectable in gravity wave experiments of the near future.
