We study equilibrium sequences of close binary systems composed of identical polytropic stars in Newtonian gravity. The solving method is a multi-domain spectral method which we have recently developed. An improvement is introduced here for accurate computations of binary systems with stiff equation of state ($\gamma>2$). The computations are performed for both cases of synchronized and irrotational binary systems with adiabatic indices $\gamma=3,~2.5,~2.25,~2$ and 1.8. It is found that the… 
Spectral Methods for Numerical Relativity
TLDR
This paper focuses on a class called spectral methods in which, typically, the various functions are expanded in sets of orthogonal polynomials or functions, and presents results obtained by various groups in the field of general relativity by means of spectral methods.
Review of Conformally Flat Approximation for Binary Neutron Star Initial Conditions
The spatially conformally flat approximation (CFA) is a viable method to deduce initial conditions for the subsequent evolution of binary neutron stars employing the full Einstein equations. Here we

Fast hyperbolic relaxation elliptic solver for numerical relativity: Conformally flat, binary puncture initial data
We introduce NRPyElliptic , an elliptic solver for numerical relativity (NR) built within the NRPy+ framework. As its first application, NRPyElliptic sets up conformally flat, binary black hole (BBH)
