Erratum: Nonstrange quark stars from an NJL model with proper-time regularization[Phys. Rev. D 100, 123003 (2019)]

摘要

In this paper, we have concluded that our calculations on the Λ for a 1.4-solar-mass star are “within the interval (200 < Λ < 800) [1] and the interval (0 < Λ < 630) for large component spin, and satisfy the constraint with Λ = 300_(?230)~(+420) when restricting the magnitude of the component spins from the analysis of GW170817 [2]”. But those citations are not all appropriate here for our calculated results. After discussion with the author of a recent work “probing up-down quark matter via gravitational wave” [3], and rereading on the work in Ref. [2], our calculated results can only fit to Λ < 800 for the low spin prior. This is because of our misunderstanding of data in those cited works.
