Neutron Stars and the High Density Equation of State
T. Klahn, C. D. Roberts, D. B. Blaschke +1
One of the key ingredients to understand the properties of neutrons stars is the equation of state at finite densities far beyond nuclear saturation. Investigating the phase struct…
Equation of state at high densities and modern compact star observations
D. Blaschke, T. Klahn, F. Sandin
Recently, observations of compact stars have provided new data of high accuracy which put strong constraints on the high-density behaviour of the equation of state of strongly inte…
Accessibility of color superconducting quark matter phases in heavy-ion collisions
D. B. Blaschke, F. Sandin, V. V. Skokov +1
We discuss a hybrid equation of state (EoS) that fulfills constraints for mass-radius relationships and cooling of compact stars. The quark matter EoS is obtained from a Polyakov-l…
The phase diagram of three-flavor quark matter under compact star constraints
D. Blaschke, S. Fredriksson, H. Grigorian +2
The phase diagram of three-flavor quark matter under compact star constraints is investigated within a Nambu--Jona-Lasinio model. Local color and electric charge neutrality is impo…
Core collapse supernovae in the QCD phase diagram
T. Fischer, D. Blaschke, M. Hempel +9
We compare two classes of hybrid equations of state with a hadron-to-quark matter phase transition in their application to core collapse supernova simulations. The first one uses t…
The observational legacy of preon stars - probing new physics beyond the LHC
F. Sandin, J. Hansson
We discuss possible ways to observationally detect the superdense cosmic objects composed of hypothetical sub-constituent fermions beneath the quark/lepton level, recently proposed…
