标题： Why Wide Jupiter-Mass Binary-Objects Cannot Form

摘要： $N_{\rm pp} = 40$质量木星的双星天体（JuMBOs）与$N_{\rm p} = 500$无伴星质量木星天体（JMOs）在织女星星团中心区域的发现引发了关于它们起源的疑问\cite{2023arXiv231001231P}。\citet{2024NatAs...8..756W}认为，围绕同一颗恒星运行的两颗行星因近距离相遇而被剥离的速率可以解释织女星星团中约一半观测到的JuMBOs。尽管他们的截面计算与我们的结果一致\citep{2024ScPA....3....1P}，但不能将他们的结果推广到聚类环境中，因为这忽略了聚类环境中后续相遇导致的JuMBOs解离。通过所提出的场景形成JuMBOs的能力要么需要另一种形成机制，要么观测到的JuMBOs需要彻底确认。 显示英文摘要

摘要： The discovery of $N_{\rm pp} = 40$ Jupiter-mass binary objects (JuMBOs) alongside $N_{\rm p} = 500$ free-floating Jupiter-mass objects (JMOs) in the Trapezium cluster's central portion raises questions about their origin \cite{2023arXiv231001231P}. \citet{2024NatAs...8..756W} argue that the rate at which two planets orbiting the same star are stripped by a close encounter can explain about half the observed JuMBOs in the Trapezium cluster. Although, their cross-section calculations agree with our own \citep{2024ScPA....3....1P}, one cannot extrapolate their results into clustered environments because it ignores the dissociation of JuMBOs due to subsequent encounters in the clustered environment. The inability of forming JuMBOs via the proposed scenario either calls for another formation mechanism, or the observed JuMBOs require thorough confirmation.
