Numerical simulations of equal-mass boson-star mergers reveal larger waveform deviations from black-hole binaries in late inspiral and merger, plus odd multipole excitations for certain scalar-field phases, with some signals degenerate until IMR consistency tests are applied.
The authors introduce physical field-vanishing boundary conditions for RN-AdS black holes, translate them to master-function conditions, and compute quasinormal frequencies that show new spectral features.
