Gravitational Wave ChirpBinary Inspiral · Post-Newtonian Approximation

Parameters

Chirp Mass M☉
T to Merger
Peak Freq Hz
Peak h×10⁻²¹
Physics: Post-Newtonian chirp waveform. The gravitational wave strain is
h(t) = A(t)·cos[Φ(t)] where frequency evolves as
f(t) = (1/π)(5/256·Mc⁻⁵/³·τ⁻³/⁸) with chirp mass
Mc = (m₁m₂)³/⁵/(m₁+m₂)¹/⁵. Frequency sweeps upward until merger at the ISCO.
