We comment on the paper of S. Postnikov et al. in Phys. Rev. D 82, 024016 (2010) and give a modified formula that needs to be taken into account when calculating the tidal Love number of neutron stars in case a first order phase-transition occurs at non-zero pressure. We show that the error made when using the original formula tends to zero as $p \rightarrow 0$ and we estimate the maximum relative error to be $\sim 5\%$ if the density discontinuity is at larger densities.

  1. Is the coexistence of strange quark stars and hadronic stars favored by astrophysical data? A Bayesian analysis

    nucl-th 2026-06 unverdicted novelty 6.0

    Bayesian analysis of astrophysical and laboratory data favors the two-families scenario of coexisting hadronic and strange quark stars over the one-family scenario.

  2. Properties of Stable Massive Quark Stars in Holography

    hep-ph 2025-12 unverdicted novelty 5.0

    Holographic model of massive deconfined quarks yields a stiff enough equation of state to allow stable 2-solar-mass hybrid stars with quark cores for certain nuclear phases.

  3. Primordial black holes versus their impersonators at gravitational wave observatories

    astro-ph.CO 2025-09 unverdicted novelty 4.0

    Fisher-matrix forecasts show Cosmic Explorer and Einstein Telescope can probe sub-solar PBHs to z~3 and distinguish PBHs from neutron stars up to z~0.2 via lack of tidal deformability.
