ALF2cc Initial Configuration
This neutron star is based upon the ALF2 equation of state, and is denoted as ALF2cc. We replace the region where the rest mass density $\rho_0 \ge \rho_{0s} = \rho_{0\mathrm{nuc}} = 2.7\times10^{14} \mathrm{g/cm^3}$ by $P = \sigma(\rho - \rho_s) + P_s$. Here $\sigma$ is a dimensionless parameter, $\rho$ is the total energy density, and $P_s$ is the pressure at $\rho_s$. The solutions presented in this work assme $\sigma=1.0$, i.e. a casual core, which represents the maximally compact, compressible equation of state. In this case, $T/W = 0.2501$, where $T$ and $W$ are the rotational and gravitational potential energies of the star, respectively. In addition, $\hat{A} = 5$, where $\hat{A} = A/R_e$ determines the degree of differential rotation. The constant $A$ appears in the "j-const" law, $j(\Omega) = A^2(\Omega_c-\Omega)$ and has units of length. The rotational period of the star, $P_c$, corresponds to its central angular velocity, $\Omega_c$.
