Neutron stars are the densest objects in the Universe, with M∼ 1.4 M⊙ and R∼ 12 km, and
the equation of state associated to their internal composition is still unknown. The extreme …

Massive hybrid stars with a first-order phase transition

A Li, W Zuo, GX Peng - Physical Review C, 2015 - APS

Mixed phase effects on high-mass twin stars

DE Alvarez-Castillo, D Blaschke - Physics of Particles and Nuclei, 2015 - Springer
Recently it has been found that a certain class of hybrid star equations of state with a large

Neutron star mass limit at 2M supports the existence of a CEP

D Alvarez-Castillo, S Benic, D Blaschke, S Han… - The European Physical …, 2016 - Springer
We point out that the very existence of a “horizontal branch” in the mass-radius
characteristics for neutron stars indicates a strong first-order phase transition and thus …

New Bayesian analysis of hybrid EoS constraints with mass-radius data for compact stars
