Welcome to Exostab 2.0 documentation!

Exostab (/exo’stab/) is an online service intended to simplify dynamical stability assessment for extrasolar planets. Instead of solving the gravitational three body problem over and over, Exostab pulls existing results from data-base of high precision, long term numerical orbit simulations - a 1000 CPU year’s worth of simulations to be exact - and presents regions of dynamical stability through a simple and intuitive API.

Check out the API section for further information.

A web-based tool is accessible through the Astrodynamics and Planetary Exploration (APEX) group at UIUC.

Note

This project is under active development.
