A new code for evolving relativistic fluid spacetimes |
Abstract _ |
I present a new code for solving the coupled Einstein-hydrodynamics equations to evolve relativistic, self-gravitating fluids. The Einstein field equations are solved on one grid using pseudospectral methods, while the fluids are evolved on another grid by finite differencing. I discuss implementation details, such as the communication between the grids and the treatment of stellar surfaces, and present code tests. Applications to compact binaries are discussed. |
