(Color online) Evolution of a proto-hadronic star in the gravitational-baryonic mass plane for B = 85 MeV/fm³ and σ = 30 MeV/fm². The upper (red) line represents the stellar equilibrium sequence for neutrino-free proto-hadronic stars (PHS) with . The middle (blue) line represents the cold the HS sequence. The asterisk and the full circle on these lines represent the stellar configuration with nucleation time τ = ∞ and the critical mass configuration M_cr, respectively. The lower (green) line represent the cold QS sequence. Assuming M_B =    const., the evolution of a PHS in this plane occurs along a vertical line. Stellar masses are in units of the solar mass, M_sun = 1.989 × 10³³ g.
