Post-Newtonian initial data with waves: progress in evolution. (English) Zbl 1190.83035
Summary: In [B. J. Kelly et al., Phys. Rev. D 76 024008 (2007)], we presented new binary black-hole initial data adapted to puncture evolutions in numerical relativity. These data satisfy the constraint equations to 2.5 post-Newtonian order, and contain a transverse-traceless ‘wavy’ metric contribution, violating the standard assumption of conformal flatness. We report on progress in evolving these data with a modern moving puncture implementation of the BSSN equations in several numerical codes. We discuss the effect of the new metric terms on junk radiation and continuity of physical radiation extracted.
