论文摘要
缺少$ 2 \,m _ {\ odot} $和$ 5 \,M _ {\ odot} $在紧凑型物体的联合质量分布中的M _ {\ odot} $被称为“质量差距”,主要归因于超级nova机制的特征,从而使其出生。但是,最近的观察结果表明,据报道在“差距”内的许多候选人可能会填补它,而是表明可能是真实的,或者很大程度上是由于少量统计的结果。我们在这项工作中量化了各个候选人并评估质量差距的关节概率。我们的结果表明,绝对质量差距不存在,置信度很高。将来是否相对缺乏物体存在,以及该种群如何与形成过程有关,这可能包括中子星合并,中子恒星崩溃到黑洞和其他人,还有待观察。
The lack of objects between $2\,M_{\odot}$ and $5\,M_{\odot}$ in the joint mass distribution of compact objects has been termed "mass gap", and attributed mainly to the characteristics of the supernova mechanism precluding their birth. However, recent observations show that a number of candidates reported to lie inside the "gap" may fill it, suggesting instead a paucity that may be real or largely a result of small number statistics. We quantify in this work the individual candidates and evaluate the joint probability of a mass gap. Our results show that an absolute mass gap is not present, to a very high confidence level. It remains to be seen if a relative paucity of objects stands in the future, and how this population can be related to the formation processes, which may include neutron star mergers, collapse of a neutron star to a black hole and others.
