Formulations and numerical methods for strongly magnetized compact objects in equilibrium or quasi-equilibrium, and their applications to gravitational wave astronomy

We have derived new formulations for computing equilibriums of strongly magnetized compact objects, and have been developing a set of new versatile codes, COCAL (Compact Object CALculator), for computing numerical solutions of various compact objects. Those solutions are useful not only for studying the structures of the compact objects, but also serve as initial data of simulations. The codes for computing uniformly or differentially rotating compact stars, strongly magnetized compact stars, and binary black hole initial data with the excision boundary as well as the trumpet puncture methods have been successfully developed. Calibrations of these codes are in progress, and the code for computing binary neutron stars in quasi-equilibrium is under construction.
