Gravitational Wave Inspiral — Chirp Signal

Chirp mass M☉: 28.3 Duration (s): 1.0 Play / Restart

Binary inspiral: frequency evolves as f(t) ~ (t_c−t)^{−3/8}, strain h ~ M^{5/3} f^{2/3}. The characteristic chirp (frequency and amplitude rising to merger) is a direct probe of the chirp mass M_c = (m₁m₂)^{3/5}/(m₁+m₂)^{1/5}.
