Burkert potential

class galpy.potential.BurkertPotential(amp=1.0, a=2.0, normalize=False, ro=None, vo=None)[source]

BurkertPotential.py: Potential with a Burkert density

\[\rho(r) = \frac{\mathrm{amp}}{(1+r/a)\,(1+[r/a]^2)}\]
__init__(amp=1.0, a=2.0, normalize=False, ro=None, vo=None)[source]




initialize a Burkert-density potential


amp - amplitude to be applied to the potential (default: 1); can be a Quantity with units of mass density or Gxmass density

a = scale radius (can be Quantity)

normalize - if True, normalize such that vc(1.,0.)=1., or, if
given as a number, such that the force is this fraction of the force necessary to make vc(1.,0.)=1.

ro=, vo= distance and velocity scales for translation into internal units (default from configuration file)
