Comment on "Brown Dwarfs, Quark Stars, and Quark-Hadron Phase   Transition"
  Recently, Cottingham, Kalafatis and Vinh Mau proposed, in the framework of the Lee-Wick model, a scenario of formation of quark stars in the cosmological quark-hadron phase transition with high degree of supercooling. We show here that the cosmological quark-hadron phase transition in the Lee-Wick model with such a high degree of supercooling cannot be completed. No quark stars could be formed in this scenario.
