galpy.potential.Potential.ttensor

Potential.ttensor(R, z, phi=0.0, t=0.0, eigenval=False)[source]

Calculate the tidal tensor Tij=-d(Psi)(dxidxj)

Parameters:

  • R (float or Quantity) – Galactocentric radius

  • z (float or Quantity) – height

  • phi (float or Quantity, optional) – azimuth (default: 0.0)

  • t (float or Quantity, optional) – time (default: 0.0)

  • eigenval (bool, optional) – return eigenvalues if true (default: False)

Return type:

Tidal Tensor
