Soliton stars at finite temperature

We investigate the properties of soliton stars in the Lee-Wick model when a temperature dependence is introduced into this model. It is found that at some critical temperature $T_c\sim 100-200$ MeV, a first-order phase transition occurs leading to the formation of soliton stars with characteristics similar to those considered by Lee and Pang but with a much smaller mass and size. We study the evolution of these soliton stars with the temperature from the early Universe to the present time.
