“…R = 13.7 +2.6 −1.5 km with mass 2.08 ± 0.07M ⊙ (Miller et al 2021) and R = 12.39 +1.30 −0.98 km with mass 2.072 +0.067 −0.066 M ⊙ (Riley et al 2021) were noted for the heavier pulsar PSR J0740+6620. The methodology lower bound on the maximum NS mass for the black-widow pulsar PSR J0952-0607 (Romani et al 2022) surpasses any prior measurements, including M max = 2.35 ± 0.17M ⊙ for PSR J2215-5135 (Linares et al 2018;Patra et al 2023). If the observational bounds are credible, stiffer EoSs are needed to support the NS with a higher mass 2M ⊙ .…”
