Henon-Heiles potential

class galpy.potential.HenonHeilesPotential(amp=1.0, ro=None, vo=None)

Class that implements a the Henon & Heiles (1964) potential

\[\Phi(R,\phi) = \frac{\mathrm{amp}}{2}\,\left[R^2 + \frac{2\,R^3}{3}\,\sin\left(3\,\phi\right)\right]\]

__init__(amp=1.0, ro=None, vo=None)

Initialize a Henon-Heiles potential

Parameters:

• amp (float, optional) – Amplitude to be applied to the potential (default: 1.)

• ro (float or Quantity, optional) – Distance scale for translation into internal units (default from configuration file).

• vo (float or Quantity, optional) – Velocity scale for translation into internal units (default from configuration file).
