Boiling QCD in supernova explosions and merger events

n a recent article [1] we have demonstrated that a first order
deconfinement phase transition (like boiling water) acts as an explosion
mechanism for very massive stars (50 M_sun), thus solving the
long-standing puzzle of the unknown explosion mechanism.
With the same EoS we were able to show that the postmerger gravitational
wave (GW) signal shows a significant deviation from the systematics
of peak frequency vs. radius of the source that was obtained for purely
hadronic equations of state [2]. Thus we could suggest an observable
signal for a strong phase transition in a compact star merger that
could be verified or falsified as soon as postmerger GW will be detected.
I will explain the theory background for the corresponding hybrid
quark-hadron matter EoS [3] that gives these interesting features and
discuss the possible implications for the structure of the QCD phase
diagram.
