de_dt
- legwork.evol.de_dt(e, times, beta, c_0)[source]
Compute eccentricity time derivative
Computes the evolution of the eccentricity from the emission of gravitational waves following Peters & Mathews (1964) Eq. 5.13
- Parameters
- efloat
Initial eccentricity
- timesfloat/array
Evolution timestep. Not actually used in function but required for use with scipy’s
scipy.integrate.odeint()- betafloat
Constant defined in Peters and Mathews (1964) Eq. 5.9. See
legwork.utils.beta()- c_0float
Constant defined in Peters and Mathews (1964) Eq. 5.11. See
legwork.utils.c_0()
