Chirp d’onde gravitationnelle

Inspiral binaire post-newtonien : forme d’onde h(t), masse de chirp et orbite coalescente en WebGL.

About this tool

Generate a leading-order gravitational-wave chirp from a circular binary.

  • Chirp mass M_c = (m₁ m₂)3/5/(m₁+m₂)1/5
  • Frequency vs time-to-coalescence: f(τ) ∝ M_c−5/8 τ−3/8
  • Strain amplitude h ∝ (M_c5/3/D) f2/3 (face-on quadrupole)

Defaults resemble GW150914-like masses and distance. The waveform is tapered near the ISCO; no ringdown. Press Run for the plot and animation.
