Does a hadron-quark phase transition in dense matter preclude the existence of massive neutron stars ?. (arXiv:1304.6907v1 [astro-ph.HE]):
We study the impact of a hadron-quark phase transition on the maximum
neutron-star mass. The hadronic part of the equation of state relies on the
most up-to-date Skyrme nuclear energy density functionals, fitted to
essentially all experimental nuclear mass data and constrained to reproduce the
properties of infinite nuclear matter as obtained from microscopic calculations
using realistic forces. We show that the softening of the dense matter equation
of state due to the phase transition is not necessarily incompatible with the
existence of massive neutron stars like PSR J1614-2230.
