Quickly compute properties of von Zeipel-Lidov-Kozai oscillations in triple systems at the quadrupole expansion order and in the non-test-particle limit.
Usage:
python(3) ZLK.py --mode X
where mode should be set to 0 to use the (semi)analytic methods to compute the minimum and maximum eccentricities, and the eccentricity oscillation timescale. Initial parameters can be specified with the additional arguments
--e0
: initial inner eccentricity
--g0
: initial inner argument of periapsis (units: rad)
--theta0
: cosine of the initial relative inclination
--gamma
: ratio of angular momenta
For information on more options (other "modes"), please refer to the help: type
python(3) ZLK.py --help
Note: in order to carry out numerical integrations of the equations of motion, SecularMultiple
