TES is an n-body integration package for modelling the evolution of exoplanet systems. TES is a highly rapid and precise integration scheme when used to approximate the behaviour of systems with a dominant central mass, e.g. a planetary system.
TES is integrated within the wider REBOUND integration package for ease of use and to enable additional functionality. TES can be run natively in C or driven through an intuitive python interface. An example of the Apophis flyby of the Earth in 2029 can be found in examples/apophis_flyby and easily compiled and run by navigating to this directory and using the command make; ./rebound. The python interface is also just as simple to install, from the top level directory call make clean; make; python setup.py build; pip install -e . and TES will be installed as a python library that can be imported with the python command import rebound.
If you use this code or parts of this code for results presented in a scientific publication, we would greatly appreciate a citation.
