Comment on "Tidal Love numbers of neutron and selfbound quark stars"
Abstract
We comment on the paper of S. Postnikov et al. [Phys. Rev. D 82, 024016 (2010), 10.1103/PhysRevD.82.024016] 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 phasetransition occurs at nonzero pressure. We show that the error made when using the original formula tends to zero as p →0 , and we estimate the maximum relative error to be ∼5 % if the density discontinuity is at larger densities.
