Hadron-Quark Crossover and Massive Hybrid Stars

Recently, Masuda et al. (arXiv:1212.6803) have elaborated on a method for constructing a hadron-to-quark matter transition suggested by them earlier (arXiv:1205.3612) which seemingly provides an approach to construct an equation of state that is very robustly stiff enough to allow hybrid stars with masses well above 2 solar masses. In the spirit of a journal club, we discuss this paper and the drawbacks implied by the suggested method by comparing with standard thermodynamics of phase transitions (Gibbs constructions). We invite all group members and interested audience to attend the seminar well-prepared for participating in the discussion.
