Fermi Degenerate Antineutrino Star Model of Dark Energy

Figure 5

Likelihood contours for the central density (ρ₀) of the antineutrino star, the initial radial expansion velocity of matter (), and the effective electron neutrino mass . The SNe Ia data constrain the effective electron neutrino mass to high statistical precision,  meV/c². However, the systematic uncertainty associated with model assumptions likely dominates over the statistical uncertainty.
