| Research Abstract |
Formulations for computing quasi-equilibrium of magnetized binary neutron stars and their generalized thermodynamic laws are derived. We develop a new code, Cocal-Compact Object CALculator, to calculate structures of compact objects in quasi-equilibriums, and successfully compute, for example, triaxially deformed rapidly rotating neutron stars. Quasi-equilibrium solutions for binary neutron stars are also calculated, and they are provided as initial data sets for simulations of binary inspirals. Gravitational waveforms obtained the simulations are analyzed.
