Pion stars from lattice QCD

Gergely Endrodi

A novel type of compact star is proposed that consists of a Bose-Einstein
condensate of charged pions and a gas of electrons. The equation of state and
the mass-radius relation of such objects can be determined from first-principle
lattice QCD simulations. It is demonstrated that pion star matter exhibits
gravitationally bound configurations and is metastable against electroweak
decays. The ingredients of the lattice simulations as well as of the
construction of the stars will be discussed in detail.
