evolve_f_orb_circ
- legwork.evol.evolve_f_orb_circ(f_orb_i, m_c, t_evol, ecc_i=0.0, merge_f=<Quantity 1.e+09 Hz>)[source]
Evolve orbital frequency for
t_evol
time.This gives the exact final frequency for circular binaries. However, it will overestimate the final frequency for an eccentric binary and if an exact value is required then
legwork.evol.evol_ecc()
should be used instead.- Parameters
- f_orb_ifloat/array
Initial orbital frequency
- m_cfloat/array
Chirp mass
- t_evolfloat
Time over which the frequency evolves
- ecc_ifloat/array
Initial eccentricity
- merge_ffloat
Frequency to assign if the binary has already merged after
t_evol
- Returns
- f_orb_fbool/array
Final orbital frequency
