AccelHarmonic

class ssapy.gravity.AccelHarmonic(body, n_max=None, m_max=None)[source][source]

Bases: Accel

Acceleration due to a harmonic potential.

Parameters:

  • body (ssapy.Body) – The body.

  • n_max (int) – The maximum degree of the potential.

  • m_max (int) – The maximum order of the potential.

Methods Summary

__call__(r, v, t[, _E])

Evaluate acceleration at particular place/moment.
