Convective stability analysis of massive neutron stars formed in binary mergers
Criterion I
Fig. 1: The time evolution of the Schwarzschild criterion (first column), the Reyleigh-Solberg criterion (second column), and Criterion I (third column) in the $x\text{-}z$ (first row) and $x\text{-}y$ (second row) planes for the model APR4-135135. The black dashed line marks the place where the criterion equals zero. The black solid line represents the density contour at restmass density $\rho = 10^{11.5} \, \mathrm{g\,cm^{-3}}$.
Fig. 2: Same as Fig. 1 but for the model MPA1-135135.
Fig. 3: Same as Fig. 1 but for the model SLy4-128128.
Criterion II
Fig. 4: The time evolution of Criterion II in the $x\text{-}z$ (first row) and $x\text{-}y$ (second row) planes for the model APR4-135135. The black dashed line marks where the criterion equals zero. The black solid line represents the density contour at $\rho = 10^{11.5} \, \mathrm{g\,cm^{-3}}$.
Fig. 5: Same as Fig. 1 but for the model MPA1-135135.
Fig.6: Same as Fig. 4 but for the model SLy4-128128.
