AI 中文总结
本文针对带电夸克星径向稳定性方程的错误解进行修正，重新计算本征频率，发现其稳定范围大于原预测，且部分质量-半径关系满足最新观测约束。
AI 中文摘要
我们评论带电夸克星文献中的一个错误：该错误导致《物理评论D》第102卷第3期034031页（2020年）的研究，使得《物理评论D》第104卷第12期123007页（2021年）的研究得出了带电相互作用夸克星径向稳定性方程的错误解。在这篇评论文章中，我们重新计算了广义相对论框架下带电相互作用夸克星的基频径向本征频率，并讨论其与前述研究结果的任何偏差。多数定性趋势保持不变，但给定分支上最大质量与稳定点之间的间隔幅度可能发生显著变化。我们还注意到，前述研究中所有无稳定解的分支，在修正后的对应分支中均存在稳定解。最终结果是，在所有研究案例中，带电夸克星的稳定范围均大于最初预测值。我们还对比了四项先前研究未纳入的最新观测约束，发现我们获得的部分质量-半径关系满足这些约束。
英文摘要
We comment on an error in the charged quark star literature ( Phys. Rev. D, 102(3):034031, 2020 ) that resulted in erroneous solutions to the radial stability equations for charged interacting quark stars in ( Phys. Rev. D, 104(12):123007, 2021 )[2]. In this comment article we recalculate the fundamental radial eigenfrequencies for charged, interacting quark stars in general relativity and discuss any departure from previous results [2]. Most of the qualitative trends persist, but the magnitudes of the separation between the maximum mass and stability points on a given branch can change significantly. We also note that all branches in [2] that contained no stable solutions now have stable solutions in their corrected counterparts. The net effect is that in all of the studied cases charged quark stars have a greater range of stability than originally predicted. We also compare four recent observational constraints not included in previous studies, and find that these constraints are satisfied by a subset of the mass-radius relations we obtain.
