Plummer

class peebee.models.Plummer(**kwargs)

Bases: Model

Plummer sphere mass distribution.

Implements the Plummer (1911) model commonly used for globular clusters and other spherical stellar systems. Allows for optional center offset.

Methods Summary

accel(x, y, z, **kwargs)	Compute Plummer sphere acceleration.
density(x, y, z, **kwargs)	Compute Plummer density profile.
