Dyad

Dyad is a two-body dynamics and binary-star statistics package for astrophysicists.

It provides:

1. a class object, dyad.Orbit, that represents the bound orbit of a body in a gravitational central potential,

2. a class object, dyad.TwoBody, that represents the component orbits of a bound gravitational two-body system,

3. a suite of probability distributions, dyad.stats, for the orbital properties of a population of binary stars, and

4. a suite of utility functions for computing derived properties.
